Explore nuclear multiple chirality in $A\sim 60$ mass region within covariant density functional theory

Abstract

The nuclear multiple chirality in $A\sim 60$ mass region is explored by the adiabatic and configuration-fixed constrained covariant density functional theory for cobalt isotopes. The potential-energy curves and triaxiality parameters $\gamma$ as functions of the deformation parameter $\beta$ in ${}^{54,56,57,58,59,60}$Co are obtained. It is found that there are high-$j$ particle(s) and hole(s) configurations with prominent triaxially deformed shapes in these isotopes. This points towards that the existence of chirality or multiple chirality in $A\sim 60$ mass region are highly anticipated.
