形变奇质量核是研究单粒子自由度和集体自由度之间相互作用的理想例子。受最近奇质子核素171 Tm高自旋实验数据的启发，我们利用投影壳模型（PSM）计算了基态和其他基于同质异能态的能带结构.除了通常的四极-四极力的哈密顿量，我们采用十六极-十六极（HH）的相互作用，在一个自洽的方式与十六极变形的变形基础。结果表明，PSM计算能很好地描述已知的实验数据。讨论了HH力对准粒子同质异能态的影响。
Deformed odd-mass nuclei are ideal examples where the interplay between single-particle and collective degrees of freedom can be studied. Inspired by the recent experimental high-spin data in the odd-proton nuclide171Tm, we perform projected shell model (PSM) calculations to investigate structure of the ground band and other bands based on isomeric states. In addition to the usual quadrupole-quadrupole force in the Hamiltonian, we employ the hexadecapole-hexadecapole (HH) interaction, in a self-consistent way with the hexadecapole deformation of the deformed basis. It is found that the known experimental data can be well described by the PSM calculation. The effect of the HH force on the quasiparticle isomeric states is discussed.
