Influence of the unique-parity states on the collectivity of low-lying states
Abstract
The importance of the unique-parity single-particle level in the description of nuclear collectivity is stressed in the framework of the nucleon-pair shell model truncated to the SD subspace. It is found that with the shell model Hamiltonian which includes the single-particle energy term, the unique-parity single-particle level has to be included to describe the low-lying collective states reasonably.
