A general solution of the Bohr collective Hamiltonian

Abstract

Eigensolutions of the Bohr collective Hamiltonian are obtained by expanding its eigenstates on a truncated basis which is adaptable to the most general potential energy and mass parameter surfaces. After a short survey of the method in use, its numerical accuracy is assessed from results obtained in some selected cases. The results of preliminary calculations for154, 156, 158Er and232Th nuclei (where the potential energy surfaces are deduced from self-consistent calculations using the Skyrme SIII force) are also briefly discussed.
