Nuclear hexacontatetrapole deformation effects on the rotational structures at large deformations in 158Er

Abstract

Effect of the nuclear hexacontatetrapole deformation on the rotational structure of [Formula: see text]Er is analyzed using the Cranked Nilsson–Strutinsky (CNS) approach. Our calculations show that it will lead to a decrease of the total energy of [Formula: see text] 700[Formula: see text]keV in the strongly deformed (SD) region and only a few keV in the triaxial superdeformed (TSD) region. Therefore, it is concluded that the effect of the hexacontatetrapole deformation is significant for SD shapes and essentially negligible for TSD shapes.
