偶偶核γ不稳定集体激发的新公式

A New Formula for the γ-Soft Collective Excitation in Even-Even Nuclei

从Ｂｏｈｒ哈密顿出发，通过引入一个有效势，得到了一个适用于γ不稳定核的新公式．将此公式与标准γ不稳定核的ｙｒａｓｔ带比较，相对误差不超过百分之五．

Starting from the Bohr Hamiltonian, a new formula is obtained to describe the γ-soft nuclei in terms of introducing an effective potential. The formula is fitted to the data.of the yrast lines of standard γ-soft nuclei.The relative errors are not beyond five percent.
