摘要: The total-Routhian-surface (TRS) calculation provides a powerful theoretical tool to describe the collective rotations of nuclei. It gives straightforward way determine nuclear deformation which can change with increasing rotational frequency. In most cases, however, TRS calculations conventional pairing approach (e.g., Bardeen-Cooper-Schrieffer pairing) encounter nonconvergence problem when applied sidebands are built on broken-pair excited intrinsic configurations. To overcome this problem, we have developed particle-number-conserving method in correlation is treated merit shell model. paper, present first results calculations, focusing ${}^{178}$W nucleus, investigating changes and incurred effects behaviors sidebands.
