(ionized H atom) strikes a gold nucleus, causing the nucleus to expand
and fly apart. (Courtesy, Victor Viola, Indiana University)
Phase diagrams for two analogous systems: (left) the nucleons in a
krypton nucleus interacting via the strong nuclear force (EOS was an
experiment carried out 10 years ago at LBNL); and (right) Krypton atoms
in a gas interacting via the electromagnetic interaction. r and rc are the density and critical density, respectively. Likewise,
T and Tc are the temperature and critical temperature,
respectively. (Courtesy, LBNL)
