In the present work, we investigate the general properties of low-lying experimental bands in three isotones, 155Dy , 156Ho , 157Er , at high spin within the cranked Nilsson-Strutinsky formalism. The excitation energies of the yrast bands have been compared with the experimental findings, and good agreements are observed. Our calculations show that with increasing total nuclear spin, the collectivity decreases gradually leading to the termination. In addition, nuclei with 10–12 particles outside the closed core terminate within configurations with no hole in the core.
