Hans Frauenfelder

from Wikipedia, the free encyclopedia

Hans Emil Frauenfelder (born July 28, 1922 in Neuhausen am Rheinfall ) is a Swiss-American physicist.

Frauenfelder studied at the ETH Zurich , where he graduated in 1947 and received his doctorate in 1950 with a thesis on the investigation of surface processes with radioactivity under Paul Scherrer . He also heard from Gregor Wentzel and Wolfgang Pauli there . He was then an assistant there before he went to the United States at the University of Illinois at Urbana-Champaign , where he became Assistant Professor in 1952, Associate Professor in 1956 and Professor in 1958. From 1978 he was a member of the Center for Advanced Study there and since 1995 he has been Professor Emeritus for Physical Chemistry and Biophysics there. In 1992 he went to Los Alamos National Laboratory , where he was director of the Center for Nonlinear Studies from 1995 to 2003. Then he was a Senior Fellow in the theory department. In 1958/59, 1963 and 1973 he was a scientist at CERN . In 1961 he became a Fellow of the American Physical Society .

In Switzerland he developed the Perturbed Angular Correlation ( PAC spectroscopy ) of gamma emitters in solids with, after the work of Brady and Deutsch in 1947. In the USA he switched to nuclear physics, studied parity violation and applied the Mössbauer effect in experiments . He later turned to biophysics and the study of proteins.

He has been a member of the National Academy of Sciences since 1975 and of the American Philosophical Society since 1981 , and of the Leopoldina and the American Academy of Arts and Sciences since 1979 . In 1981 he was elected a Fellow of the American Association for the Advancement of Science . He is an external member of the Royal Swedish Academy of Sciences . In 1992 he received the Max Delbrück Prize in Biophysics from the American Physical Society. In 2007 he received the Willis E. Lamb Prize .
