Reconsideration of enhancement of sd dominance in interacting boson models
Abstract
The enhancement of sd dominance in interacting boson models for nuclei is shown to be due primarily to the relatively small single-particle energy gap between the s boson and the d boson compared to larger single-particle energy gaps between the s and d bosons and bosons with l≥4 when a repulsive pairing interaction between the boson pairs is introduced.
