Rotational limit of the interacting two-vector boson model

Abstract

The rotational limit of the interacting two-vector-boson model is investigated. This limit arises if the Hamiltonian is 'pseudospin' invariant and corresponds to the following reduction chain of subgroups: U(6) contains/implies U(3)(+)U(2) contains/implies O(3). Analytic relations for the energies and E2 transition probabilities within the ground-state band, the beta and gamma vibrational bands and between the vibrational bands for the strongly deformed even-even nuclei are obtained.
