Aage Bohr

Aage Niels Bohr ( born June 19, 1922 in Copenhagen, † September 8, 2009 in Copenhagen) was a Danish physicist and Nobel laureate at the University of Copenhagen.


Aage Bohr was the son of Niels Bohr, he still acted as a student in October 1943 into exile in America and England as secretary and assistant. In 1946 he received his diploma in Copenhagen. In 1948 he was at the Institute for Advanced Study in Princeton and thereafter until 1950. At Columbia University at the invitation of Isidor Isaac Rabi, who investigated the hyperfine structure of deuterium This quadrupole moments of the core were measured, which were much higher than the possible Einteilchenwerte and pointed to collective excitations. Through experimental progress could then be discovered around 1953 rotational bands directly in nuclear spectra and transitions between rotational excitations are generated directly by Coulomb excitation, which yielded a wealth of new material for the study of collective excitations. 1956-1992 he was a professor at the University of Copenhagen, after the death of his father Niels Bohr 1963-1970, he was Head of the local Niels Bohr Institute ( NBI) and from 1975 to 1981 director of the NORDITA, the " Nordic Institute for Theoretical Atomic and Molecular Physics ", which was founded in 1957 and works closely with the NBI.

He received in 1975 along with Ben R. Mottelson and James Rainwater the Nobel Prize in Physics "for the discovery of the connection between collective motion and particle in atomic nuclei and the development of the theory of the structure of atomic nuclei based on this connection ".

With his longtime colleague Ben Mottelson, he developed a model of collective excitations in atomic nuclei as a common (often deformed, that is no longer spherically symmetric ) potential of the nucleons with their own rotational and vibrational states. They examined inter alia the interaction of collective and single-particle excitations, for example, in heavy lead nuclei (close to the stable magic numbers of the shell model ) and turned one of the first BCS theory of superconductivity in nuclear physics (as well as the Russians Arkady Migdal and Spartak Belyaev ).

In addition to the Nobel Prize he received in 1960 the Dannie Heineman Prize, the 1970 Oersted Medal and 1976 Ole Römer medal. He was awarded, together with five other winners of the Atoms for Peace Award on 14 May 1969. In 1981 he was elected a member of the German Academy of Sciences Leopoldina, was elected.

He was married in 1950 and had three children.
