稀土原子核生成$_{50}$ Sn-子体及其壳层效应的理论研究
Theoretical Studies of Rare-Earth Nuclei leading to $_{50}$Sn-Daughter Products and the Associated Shell Effects
摘要：
本文研究了稀土原子核的团簇衰变，目的是寻找子核$_{50}$ Sn的中子魔壳。研究了$^{100}$ Sn和$^{132}$ Sn的放射性，以找到最可能的簇衰变和新中子壳层的可能性（如果有的话）。对于这里考虑的广泛的母核（从Ba到Pt），$^{112}$ Ba的$^{12}$ C和$^{210}$ Pt母核的$^{78}$ Ni被预测为最可能的簇（最小衰变半衰期），分别涉及$^{100}$ Sn和$^{132}$ Sn子核。此外，$^{122}$ Sm的$^{22}$ Mg衰变被指示为$^{100}$ Sn-子体衰变的第二最佳可能性。除了这些已知的幻壳层（Z=50，N=50和82）外，还发现了一个Z=50，N=66的新幻壳层（$^{116}$ Sn子体），它是由$^{180}$ Pt母体衰变而来的$^{64}$ Ni。
英文摘要：
Cluster decays of rare-earth nuclei are studied with a view to look for neutron magic shells for the $_{50}$Sn nucleus as the daughter product always. The $^{100}$Sn and $^{132}$Sn radioactivities are studied to find the most probable cluster decays and the possibility, if any, of new neutron shells. For a wide range of parent nuclei considered here (from Ba to Pt) $^{12}$C from $^{112}$Ba and $^{78}$Ni from $^{210}$Pt parent are predicted to be the most probable clusters (minimum decay half-life) referring to $^{100}$Sn and $^{132}$Sn daughters, respectively. Also, $^{22}$Mg decay of $^{122}$Sm is indicated at the second best possibilty for $^{100}$Sn-daughter decay. In addition to these well known magic shells (Z=50, N=50 and 82), a new magic shell at Z=50, N=66 ($^{116}$Sn daughter) is indicated for the $^{64}$Ni decay from $^{180}$Pt parent.
