The SD-pair shell model (SDPSM) is shown to reproduce approximately typical spectra, E2 transition strengths, and wave functions of the U(5), SO(6), and SU(3) limits of the interacting boson model (IBM). Consequently, the analysis confirms that the IBM has a sound shell-model foundation; it also demonstrates that the truncation scheme adopted in the SDPSM is reasonable. ©2005 The American Physical Society.
