Study on Superdeformed Nuclei in A ~190 Region with Cranking Bohr Mottelson Hamiltonian
-
摘要: 用推转玻尔-莫特森哈密顿量研究了A~190区20个核的55条超形变带.通过拟合实验测得的E2跃迁能量值,确定了各带的能级自旋,得到了质量参量B1和硬度参数C0.B1和C0都显示出明显的奇偶性. superdeformed bands in 20 nuclei of the A ~190 region are studied with formulas derived from the Cranking Bohr Mottelson Hamiltonian. From fitting the experimental E γ , the level spins are determined and mass parameter B 1 and rigidity parameter C 0 are obtained. The B 1 and C 0 values show clear odd even effects.
