摘要
本文用以玻色子展开和MJS代换为基础的微观方案研究~(122-134Ba偶同位素系列核谱从转动型向γ-不稳型的相变,直接检验了由微观方案导出的IBM-2哈密顿量的合理性。
The phase transition of low-lying energy spectrum structure from rotational to r-unstable for ^(122-134)Ba isotopes are studied within the framework of microscopic approach based on Boson expansion and MJS substitution. The rationality of the IBM-2 Hamiltonian that is derived from the microscopic approach is also tested.
