1949
Columbia Nuclear Structure Research
Takes a research position at Columbia University, where contact with James Rainwater helps focus his attention on nonspherical atomic nuclei and nuclear magnetic properties.
1951
Angular Momentum Quantization in Heavy Nuclei
Publishes a model of heavy nuclei allowing nonspherical average fields and quantized angular motion, improving explanations of large nuclear quadrupole moments.
1952
Nuclear Surface Oscillation Coupling
Publishes a theory coupling oscillations of the nuclear surface to the motion of individual nucleons, developing the connection between collective and particle behaviour.
1953
Collective Nuclear Model
Co-develops a model combining individual particles with collective nuclear motion.
Nuclear Rotation and Vibration
Explains nuclear spectra through rotations and vibrations of deformed nuclei.
1954
Doctorate on Rotational Nuclear States
Completes a doctoral thesis on rotational states of atomic nuclei, consolidating theoretical work on deformation, angular momentum and collective nuclear motion.
1956
Professor of Physics
Is appointed professor of physics at the University of Copenhagen and continues a long-term programme of theoretical nuclear-structure research.
1963
Director of Niels Bohr Institute
Succeeds his father as director of the Copenhagen institute, preserving its international research tradition while continuing work in nuclear theory.
1969
Nuclear Structure Volume I
Publishes Nuclear Structure, Volume I, with Ben Mottelson, presenting a systematic treatment of single-particle motion and the foundations of modern nuclear structure theory.
1975
Collective Nuclear Motion Recognition
Receives recognition for connecting nuclear structure with collective behavior.
Nobel Prize in Physics
Shares the physics prize for describing collective motion in atomic nuclei.
Nuclear Structure Volume II
Publishes Nuclear Structure, Volume II, with Ben Mottelson, developing a comprehensive treatment of nuclear deformation and collective degrees of freedom.
2009
Death of Aage Bohr
Dies in Copenhagen aged eighty-seven after a career devoted to nuclear structure, collective motion, theoretical physics and international scientific collaboration.
