We study transitional patterns from the vibrational, U (5), to the rotational, SU (3), limit of the interacting boson model with a schematic Hamiltonian. The transitional behavior of low-lying energy levels, isomer shifts, E2 transition rates, and some other related quantities across the entire U (5) ↔ SU (3) transitional region are studied in detail. The analysis shows that nuclei in the critical region are soft. © 2003 Published by Elsevier B.V.
