Aage Niels Bohr
The Nobel Prize in Physics 1975
Born: 19 June 1922, Copenhagen, Denmark
Died: 8 September 2009, Copenhagen, Denmark
Affiliation at the time of the award: Niels Bohr Institute, Copenhagen, Denmark
Prize motivation: "for the discovery of the connection between collective motion and particle motion in atomic nuclei and the development of the theory of the structure of the atomic nucleus based on this connection."
Prize share: 1/3
According to modern physics, an atomic nucleus consists of nucleons - protons and neutrons. In earlier models the nucleus was depicted as being spherical, but this proved to be inaccurate. In 1950 James Rainwater postulated that the atomic nucleus can be distorted. The nucleons in the outer portions of the atomic nucleus move about in paths and interact with nucleons inside, causing the nucleus to be distorted. Independently of Rainwater, Aage Bohr arrived at the same theory and corroborated it through experiments in collaboration with Ben Mottelson in 1952 and 1953.
Their work and discoveries range from cancer therapy and laser physics to developing proteins that can solve humankind’s chemical problems. The work of the 2018 Nobel Laureates also included combating war crimes, as well as integrating innovation and climate with economic growth. Find out more.
