摘要/描述

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.
