Niels Bohr Institute

Great scientists came and went at the Institute. One thing remained constant, however Bohr himself. He was kindly, brilliant, and well connected. Thus, it was only fitting that in 1965, on Bohr s birthday, the Institute for Theoretical Physics was renamed the Niels Bohr Institute.

In 1959, Ballhausen was appointed professor of chemistry at the University of Copenhagen and director of its Institute of Physical Chemistry [Fysisk Kemisk Institut (FKI)]. The institute was located on Blegdamsvej 19, next to the Niels Bohr Institute. Ballhausen s predecessor was the reaction kineticist J.A. Christiansen. He had employed Arne E. Nielsen, who worked on chemical nucleation, and Thor A. Bak, who worked on theoretical chemical kinetics and the theory of irreversible thermodynamics. They both contributed to the positive atmosphere at the institute. Thor Bak had, in particular, a very stimulating effect on students. Yet, another important staff member was Jprgen Koefoed, who taught physical chemistry at DTU and became professor there in 1962. 

Niels Bohr studied at the University of Copenhagen and earned a master of science degree in 1909 and a doctorate degree in 1911 (at the age of twenty-six). He then went to England and worked with Joseph John Thomson at Cambridge University and with Ernest Rutherford at Victoria University in Manchester. In 1914 Bohr returned to the University of Copenhagen, where, at the age of twenty-nine, he became an assistant professor of physics (he became a full professor in 1916 and held that post until 1956). Erom 1920 onward he was the director of the university s Institute for Theoretical Physics (renamed the Niels Bohr Institute in 1965). The institute became a focal center for theoretical physics for a generation.

The history of neutron activation analysis goes back to the middle of the 1930s when it was first described by G. Hevesy and H. Levi at the Niels Bohr Institute in Copenhagen. The principle of the technique is that elements can be made radioactive by exposure to neutron irradiation. Two types of physiological processes are associated with this activation one prompt and one delayed. Classically, neutron activation analysis is based on the detection of the delayed event, viz. the characteristic radiation emitted during the decay -with a specific half-life (ti/a) - of the unstable nuclei formed by (n,y) reaction.

Pauli, Wolfgang (1900-1958) An Austrian theoretical physicist of Jewish heritage who converted to Catholicism, Pauli earned a Ph.D. at the age of twenty-one. While lecturing at the Niels Bohr Institute for Theoretical Physics, he researched relativity and quantum physics. He discovered a new law governing the behavior of atomic particles and the characteristics of matter, called the Pauli exclusion principle, for which he was awarded the 1945 Nobel Prize in Physics. During World War II, he moved to the United States and became an American citizen but later relocated to Zurich.

After the work by Marie Curie and her daughter Irene established a new field of research in the radioactivity of elements, others carried out similar experiments to begin to understand the internal stmcture of the nucleus and a period of increased research occurred in the 1930s. At the Kaiser Wilhelm Institute in Berlin and the Niels Bohr Institute in Stockholm, a drama unfolded in 1938 that ushered in the atomic age. Lise Meitner was a petite, shy Austrian girl who made friends with a...
