Number 123 (Story #5), April 9, 1993 by Phillip F. Schewe and Ben Stein THE NATIONAL LABS mostly score higher than the U.S. average in terms of citations per research paper for a variety of physical science areas, according to a study performed by the Institute for Scientific Information. For example, in the category of general physics for the period 1988-92, Brookhaven led other national labs with 9.44 citations per paper, compared to a national average of 5.80. Considering only national labs, the citation leaders in some of the other research categories included Argonne in applied physics/condensed matter, Berkeley in materials science, and Sandia in chemical physics.
