A systematic study of band structures of some odd mass Samarium isotopes with neutron numbers 91 ≤ N ≤ 95 is carried out by employing projected shell model. The theoretical results have been obtained for band head energies, energy spectra, transition energies and moment of inertia. The calculations on comparison with the experimental data show a reasonably good agreement. The band spectra and transition energies for higher spin states are also predicted in these isotopes. The calculations successfully provide good understanding of the change in structure of the yrast bands and excited bands in terms of single and multi-quasiparticle configurations. The future experimental work will test the predictions made in this paper.

一些奇质量钐的能带结构的系统的研究与中子数同位素91≤  Ñ  ≤95是通过采用投影壳模型进行。已获得了带头能量，能谱，跃迁能量和惯性矩的理论结果。与实验数据比较的计算结果显示出相当好的一致性。在这些同位素中还预测了更高自旋态的能谱和跃迁能。这些计算成功地提供了关于单带和多准粒子构型的拉谱带和激发带结构变化的良好理解。未来的实验工作将检验本文所做的预测。
