Otto Kofoed-Hansen (physicist)
Otto Kofoed-Hansen (born April 25, 1921 ; † July 21, 1990 in Copenhagen ) was a Danish experimental nuclear and particle physicist .
Life
Before studying physics in Copenhagen, he completed an apprenticeship as a goldsmith . From 1956 to 1968 he was the first head of the physics department at the Danish research center Risø. He was also Professor of Reactor Physics at the Technical University of Denmark in Lyngby from 1960 to 1968 and then Senior Physicist at CERN from 1968 to 1976 , where he was personal advisor to the General Director Willi Jentschke and from 1969 to 1972 Chairman of the Physics III Committee (for the scientific program of the synchro- cyclotron ). Even after his return to Denmark (when he was at the Risø Research Center and the Niels Bohr Institute ) he was in close contact with CERN. Most recently he was involved in the UA2 experiment.
In an early experiment with Jacob Christian Georg Jacobsen (1895–1965) he demonstrated that not only energy is dissipated by neutrinos during beta decay , but also momentum (at that time a confirmation of Wolfgang Pauli's neutrino hypothesis ). In 1950 he carried out mass separation on ion beams with Karl-Ove Nielsen (1920–1996) at the Niels Bohr Institute (as a predecessor of experiments of the ISOLDE type , online mass separation ). The facility should deliver radioactive isotopes for further investigation of Pauli's neutrino hypothesis.
In 1968 he became a Fellow of the American Physical Society . In 1989 he received the Danish Physical Society Prize.
