Prediction and formation mechanism of triaxial superdeformed nuclei for $A\sim 80$

Abstract

The three dimensional Total Routhian Surface (TRS) calculations are carried out for 64 nuclei between $70\le A\le 90$ to find triaxial superdeformed nuclei. Total of 12 nuclei were predicted to have triaxial superdeformation in which the neutron rotational energy plays a key role and the neutron shell energy plays additional role in the formation of triaxial superdeformed nuclei.
