Peter Herbert Jensen

The following reports were published in Kernphysikalische Forschungsberichte (Research Reports in Nuclear Physics), an internal publication of the German Uranverein. The reports were classified Top Secret, they had very limited distribution, and the authors were not allowed to keep copies. The reports were confiscated under the Allied Operation Alsos and sent to the United States Atomic Energy Commission for evaluation. In 1971, the reports were declassified and returned to Germany. The reports are available at the Karlsruhe Nuclear Research Center and the American Institute of Physics.

From 1954, he was a department director in the high-voltage section of the Max-Planck Institut für Chemie - Otto Hahn Institut, in Mainz, and he was a supernumerary professor at the Johannes Gutenberg-Universität Mainz.

From 1946 to 1953, Jensen was Wolfgang Gentner’s teaching assistant at the University of Freiburg; from 1953 to 1954 he was a senior assistant there. From 1947 he was a lecturer, and from 1951 he was a supernumerary professor (nichtplanmäßiger Professor) focusing on the installation of a Van de Graaff generator for experiments in nuclear physics.

In 1938, Jensen was a volunteer in Walther Bothe's Institut für Physik at the Kaiser-Wilhelm Institut für medizinische Forschung (KWImF, Kaiser Wilhelm Institute for Medical Research, reorganized and renamed in 1948 the Max-Planck Institut für medizinische Forschung), in Heidelberg. He was a teaching assistant there to Walther Bothe from 1939 to 1946. During this time, Jensen worked on the German nuclear energy project, also known as the Uranverein (Uranium Club); his work with Walther Bothe, Arnold Flammersfeld, and Wolfgang Gentner appeared as Internal Reports in the Kernphysikalische Forschungsberichte (Research Reports in Nuclear Physics) . Jensen completed his Habilitation at the Ruprecht-Karls-Universität Heidelberg in 1943. The subject of his Habilitationsschrift was on nuclear cross sections of neutron scattering experiments conducted at the University of Heidelberg.

From 1932 to 1938, Jensen studied at the Universität Göttingen and the Albert-Ludwigs-Universität Freiburg. He received his doctorate in 1938, under Georg Joos at the University of Göttingen.

Peter Herbert Jensen (28 November 1913, Göttingen – 17 August 1955, Quend) was a German experimental nuclear physicist. During World War II, he worked on the German nuclear energy project, known as the Uranverein. After the war, he was a department director in the high-voltage section of the Max Planck Institute for Chemistry, in Mainz, and a supernumerary professor at the University of Mainz.
