Mean Field Theory

Aage Bohr (1922-2009) was the central artificer of the unification of the independent (shell)- and of the collective (liquid drop)-models of the atomic nucleus. This unification constitutes the basis of what can be called the second discovery of the atomic nucleus, for which Aage Bohr and his close collaborator Ben Mottelson co-shared the 1975 Nobel Prize in Physics.

The selected papers of Aage Bohr published in the present volume provide a clear account of Aage Bohr's ideas concerning the finite quantal many-body system. These ideas changed the nuclear paradigm and connected the field of nuclear physics with that of quantum condensed matter physics as well as with Quantum Electrodynamics (QED). It has also inspired a whole generation of theorists and experimentalists, helping to create the "Copenhagen School of Nuclear Physics" which turned the Niels Bohr Institute into the Mecca for research in this subject during the 1960s and 1970s. The legacy of Aage Bohr's scientific achievements and of the school he founded are felt to this day in connection with cutting-edge research carried out at the forefront of nuclear structure and nuclear reaction studies.

Remembering the words of the sage that "We are dwarfs mounted on the shoulders of giants, so that we can see more and further than they", the present volume is an attempt at seeking illumination from Aage Bohr, through the reading of his masterfully written papers, and by reflecting over commonly experienced events. Furthermore, it may help practitioners acquire an overall view of the basis of modern theory of nuclear structure.
