利用推转玻尔-莫特逊哈密顿量对A~190区超形变核的研究表明[1~4],由拟合超形变带能谱得到的与核的内部结构密切相关的参数,质量参量B1和硬度参量C0有明显的奇偶性.为验证这些规律,我们从Nilson单粒子能级出发,用推转模型和BCS方法,首先计算了该区偶偶核超形变态质量参量B0,B1和B2,同时利用有限力程模型和微观修正方法计算了超形变态下的硬度参量C0,并进而由这些参数(经过合理调整)计算了偶偶核超形变晕带的自旋和能谱,得到的结果与实验基本符合.
The study on the super-deformable nuclei in A ~ 190 using the push-pull Bohr-Mortonson Hamiltonian shows that [1 ~ 4] the parameters that are closely related to the internal structure of the nucleus obtained by fitting the superdeformed band energy spectrum, mass Parameter B1 and hardness parameter C0 have obvious parity. In order to verify these rules, we first calculate the B0, B1 and B2 parameters of the even-handed hyperomorphism of the region from the Nilson single-particle level using the pushover model and BCS method. At the same time, using the finite-force model and the microscopic correction method The hardness parameter C0 of the super-deformed metamorphosis was calculated, and the spin and energy spectra of the hyper-deformed halo of the even-even nuclei were further calculated by these parameters (reasonably adjusted). The experimental results are in good agreement with the experimental ones.
