Title: Interplay Between Antimagnetic and Collective Rotation in {sup 58}Fe

Abstract

The self-consistent tilted axis cranking covariant density functional theory based on the point-coupling interaction PC-PK1 is applied to investigate the possible existence of antimagnetic rotation in the nucleus Fe-58. The observed data for Bands 3 and 4 are reproduced well with two assigned configurations. It is found that the interplay between antimagnetic rotation and collective motion plays an essential role in both bands due to the presence of considerable deformation. In particular, for Band 4, collective rotation is dominant in the competition with antimagnetic rotation. Moreover, it is shown that the behavior of the ratios between the dynamic moments of inertia and the B(E2) values reflects the interplay between antimagnetic and collective rotation.
