Query: The many-nucleon theory of nuclear collective structure and its
  macroscopic limits: an algebraic perspective   The nuclear collective models introduced by Bohr, Mottelson and Rainwater,
together with the Mayer-Jensen shell model, have provided the central framework
for the development of nuclear physics. This paper reviews the microscopic
evolution of the collective models and their underlying foundations. In
particular, it is shown that the Bohr-Mottelson models have expressions as
macroscopic limits of microscopic models that have precisely-defined
expressions in many-nucleon quantum mechanics. Understanding collective models
in this way is especially useful because it enables the analysis of nuclear
properties in terms of them to be revisited and reassessed in the light of
their microscopic foundations.
