摘要

已知稀土区的原子核具有强烈的变形，并显示出高自旋的旋转带。利用Hartree-Fock-Bogoliubov方法和投影壳模型研究了Yb和Er同位素$(N\ge 100)$的基态和高自旋态。在这些核中观察到大量的准粒子带，本研究探讨了其中一些可能的起源。具有可变配对的投影壳层模型可以很好地描述高自旋的基态带。

Study of ground-state bands in Er and Yb nuclei with $N\ge 100$

Nuclei in the rare-earth region are known to be strongly deformed and show rotational bands up to high spins. Ground state and high spin states of Yb and Er isotopes $(N\ge 100)$ have been studied using the Hartree–Fock–Bogoliubov approach as well as the projected shell model. A large number of quasiparticle bands are observed in these nuclei and the present study explores the possible origins of some of them. Projected shell model with variable pairing can provide a good description of the ground-state bands up to very high spins.
