Nuclear physics

In this interview, David Zierler, Oral Historian for AIP, interviews Daniel Zajfman, Institute Professor of Physics at the Weizmann Institute of Science, chair of the academic board of the Israel Science Foundation, chair of the Davidson Institute of Science Education, and Chair of the Schwartz/Reisman Science Education Center. Zajfman reviews some of the scientific and administrative challenges he has experienced during the pandemic, and the leadership role the Weizmann Institute has taken to navigate out of the crisis. He recounts his childhood in Belgium and his early interests in science, and he explains how his early inclinations toward Zionism coalesced into his decision to become an Israeli citizen and attend undergraduate school at the Technion. Zajfman discusses his undergraduate and graduate research in atomic physics, under the direction of Dov Maor. He describes his long-term interest in single ion atom collisions and his postdoctoral research at Argonne Lab, where he developed a complete analysis program that allowed the reconstruction of molecular geometries. Zajfman explains the circumstances leading to his initial appointment in the department of nuclear physics at the Weizmann Institute. He discusses his collaboration at the Max Planck Institute on dissociative recombination for a simple, cold, molecular ion, and he explains his contributions on research on gravitational collapse of interstellar clouds. Zajfman conveys his feelings, being the son of Holocaust survivors, on the significance of his collaborations in Germany. He describes the trajectory he was on that led to his tenure as president of the Weizmann Institute, and he explains how he balanced his administrative responsibilities with his strong desire to work in the lab as much as he could. Zajfman reflects on his accomplishments as president and the many responsibilities he could not foresee taking on, and he discusses Weizmann’s work with the Israeli Ministry of Science and its successful record of recruitment on the basis of the Institute being a purely “Curiosity Driven” center of science. At the end of the interview, Zajfman reflects on his contributions as president, and he conveys his confidence that the Institute has a bright future.

Moszkowski explains the origins of the division between nuclear theorists and particle theorists. He describes how he generalized Goeppert-Mayer’s delta interaction and named it the surface delta interaction which became a focus of research for many years. He then describes the social and personal upheavals he experienced during the 1960s He recounts the importance of travel and collaboration in his research, particularly his travel to Hungary, the European Center for Theoretical Studies in Nuclear Physics and Related Areas (ECT*) in Trento, and the University of Coimbra in Portugal. He recalls his interactions with many colleagues in physics including Judit Nemeth, Yoichiro Nambu, Murph Goldberger, and Murray Gell-Mann. Moszkowski describes his impressions on the status of women in physics and his biography of Goeppert-Mayer as part of a volume edited by Nina Byers and Gary Williams. Moszkowski concludes with his impressions of Enrico Fermi, Leo Szilard, Werner Heisenberg, Nambu, and Hans Bethe.

Interview with Berndt Müller, James B. Duke Professor of Physics at Duke University. The interview begins with Müller discussing his current work on quark-gluon plasma physics and the connections between nuclear physics and cosmology. Müller then recounts his family history in Germany during and after WWII, as well as his childhood in West Germany. He recalls his undergraduate studies at Goethe University Frankfurt, where it was the inspiring lectures that catalyzed his enthusiasm for physics. Müller explains the heavy ion research he was involved in at the time, as well as his master’s thesis on the Dirac equation. He recounts his first visit to Berkeley Lab in 1972 and his subsequent acceptance of a postdoc at University of Washington and a fellowship at Yale. Müller then returned to Frankfurt as an associate professor and explains how he got involved in quark-gluon plasma research. Müller talks about the creation of the RHIC and how that led him to pursue his next job in the US, landing at Duke. He discusses his involvement with the Institute of Nuclear Theory at the University of Washington, as well as his work at Brookhaven over the years. Müller recalls the pros and cons of the administrative side of academia, which he experienced as the Chair of the Faculty of Physics and then Dean of the Faculty of Natural Sciences at Duke. The interview concludes with Müller’s reflections on winning the Feshbach Prize and his predictions for the future of theoretical nuclear physics.

Interview with Herman B. White, physicist at Fermi National Accelerator Laboratory. White recounts his childhood in Tuskegee, Alabama and growing up during segregation. He discusses his early interests in science and his decision to enroll at Earlham College in Indiana as an undergraduate. White then describes his time at Michigan State University as a graduate student, during which he also held a position as a resident research associate at Argonne National Laboratory. Dr. White talks about his transition from nuclear physics to particle physics upon completing his master’s degree at MSU. He discusses the events that led him to accept a position at Fermilab rather than immediately pursue a PhD. White was the first African-American scientist appointed at Fermilab, and he recounts his early years there being mentored by Raymond Stefanski. He then describes his research fellowship at Yale and his non-traditional path to getting a PhD in 1991 from Florida State University. White talks about returning to Fermilab to work on kaon physics, and his eventual involvement in the Tevatron experiment. Toward the end of the interview, White reflects on the changes and trends he has seen in the research being done at Fermilab over the years, as well as his involvement in the National Society of Black Physicists.

Interview with Daniel R. Marlow, Evans Crawford Class of 1911 Professor of Physics, at Princeton University. Marlow recounts his childhood in Ontario and his father’s military appointment which brought his family to the United States when he was fourteen. He describes his undergraduate experience at Carnegie Mellon and the considerations that compelled him to remain for his graduate work in physics. Marlow describes his thesis research under the direction of Peter Barnes and his research visits to Los Alamos, Brookhaven, and JLab, and he surveys the theoretical advances that were relevant to his experimental work. He explains his decision to stay at CMU as a postdoctoral researcher and as an assistant professor, and he describes his interests which straddled the boundary between particle physics and nuclear physics. Marlow describes the opportunities leading to his faculty appointment at Princeton by way of the research in k+ and pi+nu nu-bar experiments at CERN. He discusses his involvement in planning for the SSC, and how the Gem collaboration was designed to find the Higgs and supersymmetry before the LHC. Marlow discusses the e787 experiment and the lesson gained that rare kaon decay experiments are more difficult than they appear at first glance. Marlow describes the origins of the Belle project in Japan at KEK and its relationship to BaBar, and he explains how finding the Higgs was the capstone to the Standard Model. He surveys the current state of play in experimental particle physics and why he encourages students to follow their interests without overly analyzing future trends in the field. At the end of the interview, Marlow describes his current interest in studying displaced vertices and long-lived particle searches, and he muses that toward the end of his career, he wants to become more of a “graduate student” so that he can focus more exclusively on the physics that is most compelling to him.

Interview with Wit Busza, Francis L. Friedman Professor of Physics Emeritus at MIT. He recounts his birth in Romania as his family was escaping Poland at the start of World War II, and his family's subsequent moves to Cyprus and then to British Palestine, where he lived until he was seven, until the family moved to England. He describes the charitable circumstances that allowed him to go to Catholic boarding school, his early interests in science, and the opportunities that led to his undergraduate education in physics at University College in London, where he stayed on for his PhD while doing experiments at CERN working with Franz Heymann. Busza describes the development of spark chambers following the advances allowed by bubble chambers, and his thesis research using the Chew-Low extrapolation to calculate the probability that the proton is a proton plus a pi-zero. He describes meeting Martin Perl and the opportunities that led to his postdoctoral position at SLAC, which he describes in the late 1960s as being full of brilliant people doing the most exciting physics and where he focused on rho proton cross-sections. Busza describes meeting Sam Ting at SLAC which led to Busza's faculty appointment at MIT, where he discovered his talent for teaching. He discusses the complications associated with the discovery of the J/psi and his developing interest in relativistic heavy ion physics, the E178 project at Fermilab to examine what happens when high energy hadrons collide, and the E665 experiment to study quark propagation through nuclear matter. Busza describes the import of the RHIC and PHOBOS collaborations, and he discusses his return to SLAC to focus on WIC and SLD. He describes the global impact of the LHC and CERN, and his satisfaction at being a part of what the DOE called the best nuclear physics group in the country. In the last part of the interview, Busza reflects on the modern advances in atomic and condensed matter physics, which were inconceivable for him to imagine at the beginning of his career, he describes the considerations leading to his retirement, and why, if could re-live his career, he would think harder about being a theorist.
