Frank Stephens
Frank S. Stephens (born June 30, 1931 in Indiana ) is an American experimental nuclear physicist and chemist .
Stephens graduated from Oberlin College with a bachelor's degree in 1955 and received a PhD in chemistry from the University of California, Berkeley in 1955 . From 1955 he was at the Berkeley Radiation Laboratory and from 1957 a full-time scientist at the Lawrence Berkeley National Laboratory (LBNL), where he became Senior Scientist and in 1995 Distinguished Scientist.
In 1959/60 he was at the Niels Bohr Institute in Copenhagen as a Ford scholar and 1970/71 visiting professor at the Ludwig Maximilians University in Munich .
With Richard M. Diamond , he developed the Gammasphere detector with a spherical arrangement of gamma-ray semiconductor detectors, which was installed on the LBNL's 88 inch cyclotron in the 1990s. Using heavy ion beams from the cyclotron, he investigated collective nuclear properties in the nuclear structure, high-spin states of nuclei, giant resonances and nuclear reactions.
In 1980 he and Richard M. Diamond received the Tom W. Bonner Prize for Nuclear Physics . He was a fellow of the American Physical Society .
