THE SD-PAIR SHELL MODEL AND INTERACTING BOSON MODEL

摘要

The SD-pair shell model (SDPSM) is shown to reproduce approximately typical spectra, JS2 transition strengths of the U(5), SO(6), SU(3) and SU*(3) limits of the interacting boson model (IBM). The shape phase transitional patterns of the IBM can also be reproduced in the SDPSM. This analysis confirms that the IBM has a sound shell-model foundation; it also demonstrates that the truncation scheme adopted in the SDPSM is reasonable.
