摘　　要：Inspired by the availability of recent experimental as well as theoretical data on the energy levels of odd-mass^151-161Pm and odd-odd^154,156Pm,we applied the theoretical framework of the projected shell model to further understand the nuclear structure of these nuclei.The calculations closely reproduced the experimental data reported for the yrast bands of these isotopes by assuming an axial(prolate)deformation of^0.3.Other properties along the yrast line,such as transition energies and transition probabilities,have also been discussed.Band diagrams are plotted to understand their intrinsic multi-quasiparticle structure,which turn out to be dominated by 1-quasiparticle bands for the odd-mass Pm isotopes and 2-quasiparticle bands for the doubly-odd Pm isotopes under study.The present study not only confirms the recently reported experimental/theoretical data,but also extends the already available information on the energy levels and adds new information regarding the reduced transition probabilities.
