Configuration-constrained total-Routhian-surface models

Abstract

Since the cranking shell model was established, it has been well developed with several key landmarks. The model has been one of the most successful models which describe the collective rotation of nuclei. Two key developments are: (1) the inclusion of pairing interaction; (2) total-Routhian-surface (TRS) calculations. Such calculations can give nuclear structure information about shape evolution with increasing rotational frequency and rotational alignments of paired nucleons. We have made significant developments based on the cranking shell model: (1) developed pairing-deformationfrequency self-consistent TRS calculations; (2) developed configuration-constrained potential-energy-surface (PES) calculations which can calculate for any excited configurations in a self-consistent way; (3) developed configuration-constrained total-Routhian-surface (TRS) calculations, achieving the self-consistent calculations of rotational motions of any excited configurations.
