Heinz-Jürgen Kluge (born April 25, 1941 in Sorau ) is a German experimental nuclear physicist at the Society for Heavy Ion Research in Darmstadt.

Life

From 1960, Kluge studied physics at the University of Bonn and Heidelberg University , where he received his diploma in 1967 and his doctorate in 1970 ( hyperfine structure of the lowest P states of alkaline earth isotopes ). As a post-doctoral student he was at CERN , where he used optical pumping techniques to investigate the properties of low-neutron mercury isotopes in the ISOLDE facility. In 1972 he became an assistant for experimental physics at the University of Mainz , where he completed his habilitation in 1975 and became professor for experimental physics in 1978. At the same time he was a senior scientist at GSI from the 1980s , where he was deputy chairman of the program committee from 1989 to 1992 and headed the atomic physics department. In 1994 he became a professor at Heidelberg University. Kluge was Research Director at GSI from 1999 to 2005. He continued to research in the ISOLDE collaboration at CERN in the 2000s .

From 1983 to 1984 he was a speaker and from 1985 to 1987 head of the ISOLDE collaboration at CERN and from 1984 to 1987 a member of the program advisory board (PSCC) at CERN.

Cleverly developed ion trap techniques for studying unstable nuclei and determining their masses, especially ISOLTRAP for the ISOLDE experiment and SHIPTRAP and HITRAP at GSI. He also made precise measurements of the beta decay properties of nuclei. He used laser spectroscopic methods, for example, to measure isotope shifts (due to different core volumes) of spectral lines.

From 1985 he was co-editor and from 2005 editor of Hyperfine Interactions . From 1999 to 2005 he was co-editor of the European Physical Journal D.

Kluge was on the Council of the German Physical Society from 1991 to 1994 .

On the occasion of his 65th birthday in 2006, the International Journal of Mass Spectrometry (IJMS) dedicated a special issue to him, which also includes a dedicated article on the history of atomic mass measurements .

Also in 2006 he received the Lise Meitner Prize for essential contributions to our knowledge of the mass, shape, size and spin of nuclei through a series of decisive, sophisticated and brilliant experiments that combine techniques from atomic and nuclear physics . In 1990 he received the Helmholtz Prize, in particular for the trace analysis of strontium 90 after the Chernobyl nuclear disaster using laser spectroscopic methods. In 2005 he became a Fellow of the American Physical Society . For 2020, Kluge was awarded the Robert Wichard Pohl Prize .
