超锕系元素核的新原子核结构特征

New nuclear structure features in transactinide nuclei

D. Bucurescu, N. V. Zamfir

摘要:

本文用双中子分离能的微分变化研究了Z > 82重核的结构演化。它表明,在一定的中子数的非单调行为,结构现象,如主壳(N = 126)和变形的子壳(N = 152)关闭。在N ~ 142处观察到另一个有趣的效应,这与先前观察到的α衰变中测量的量的有趣行为非常相关,例如该区域变形核的基态带的激发态的相对分支比和位阻因子。现有的实验数据的确证表明,另一种可能的变形亚壳层封闭。

英文摘要:

The structural evolution of the heavy nuclei, with Z > 82, is investigated by looking at the differential variation of the two-neutron separation energies. It indicates, by non-monotonous behavior at certain neutron numbers, structure phenomena such as major shell (N = 126) and deformed subshell (N = 152) closures. Another interesting effect is observed at N ~ 142, which is very well correlated with a previously observed, intriguing behavior of quantities measured in alpha decay, such as relative branching ratios and hindrance factors of excited states from the ground state band of deformed nuclei in this region. Corroboration of the existing experimental data indicates another possible deformed subshell closure.
