Charles Pence Slichter (born January 21, 1924 in Ithaca , New York - † February 19, 2018 ) was an American solid-state physicist .

Life

Slichter studied at Harvard University ( Bachelor Accounts 1946, Master 1947), where he among others, John H. Van Vleck (friend of the Slichters parents were) studied with a thesis on 1949 electron spin resonance at Edward Purcell doctorate was ( "A study of microwave absorption in paramagnetic solids "). During World War II, he worked at the Woods Hole underwater explosion research laboratory . After completing his doctorate, he became an instructor at the University of Illinois in 1949 , where he became Assistant Professor in 1951, Associate Professor in 1954 and Full Professor in 1955 (from 1968 Center for Advanced Study Professor). In 1986 he also became a professor of chemistry. In 1996 he retired , but continued to be active in research afterwards. At the University of Illinois he had more than 60 doctoral students.

Slichter is particularly known for his research on nuclear magnetic resonance (NMR) with application to investigations in solid state physics: confirmation of the BCS theory (pairing verification with lever), high temperature superconductors (also pairing verification and d-state components in addition on the s-state of the electron pairs), charge density waves, Kondo effect , surface physics and others, as well as studies on chemical physics. He was the first to confirm the Overhauser effect with Thomas Carver in 1953 and carried out the first experiment on electron-nuclear double resonance (ENDOR) with Carver . Together with Schumacher, he was the first to measure the susceptibility of the Pauli paramagnetism of conduction electrons in metals and, together with Gutowsky and McCall, discovered the J-coupling in molecules. Slichter developed a phase-sensitive detection method with high sensitivity using pulsed NMR.

In addition to experimental physics work, he also published purely theoretical work (e.g. theory of chemical shift in fluorine ).

His father Sumner Slichter (1892-1959) was a professor of economics at Harvard. His grandfather Charles Sumner Slichter (1864-1946) was also a well-known physicist at the University of Wisconsin and developed, among other things, a method for measuring the speed of groundwater currents. Slichter's brother was the manager of Bell Labs William P. Slichter; his son Jacob Slichter (* 1961) is a rock drummer.

Honors

Slichter was a member of the National Academy of Sciences since 1967 and a member of the American Academy of Arts and Sciences and the American Philosophical Society since 1969 . In 1969 he received the APS Langmuir Prize for Chemical Physics, the 1986 Triennal Prize of the International Society of Magnetic Resonance (ISMAR), the Comstock Prize for Physics in 1993, the APS Oliver E. Buckley Prize in 1996 and the DOE Prize in 1993 for excellence in solid state physics. In 2007 he received the National Medal of Science . He received honorary doctorates from the University of Waterloo (1993), Harvard (in law 1996) and the University of Leipzig (2010). From 1955 to 1961 he was an Alfred P. Sloan Fellow . He was a member of the JASON Defense Advisory Group . From 1976 to 1984 he served on the advice of the National Science Foundation and 1970 to 1995 a member of the Harvard Corporation (which directs Harvard University).
