比$^{37}$ Mg重的可能的中子晕核的研究
Examining possible neutron-halo nuclei heaver than $^{37}$Mg
摘要：
通过研究弱束缚中子球壳结构和形变壳结构，探讨了可能比$^{37}$ Mg重的最轻的偶Z奇N中子晕核.指出由于N=50球形能隙变窄，产生了几个靠近的中子单粒子能级，即1g $_{9/2}$，3s $_{1/2}$和2d $_{5/2}$，对于球形核，在这些能级中填充有弱束缚中子的核可能发生形变，很有可能出现形变的s波晕.有希望的候选物是$^{71}_{24}$ Cr $_{47}$、$^{73}_{24}$ Cr $_{49}$、$^{75}_{24}$ Cr $_{51}$和$^{77}_{26}$ Fe $_{51}$，这些核位于中子滴线内。一个有趣的可能性变形的p-波或s-波晕也建议为核$^{53}_{18}$ Ar $_{35}$。
英文摘要：
The even-Z odd-N neutron-halo nuclei, which are the possible lightest neutron-halo nuclei heavier than $^{37}$Mg, are explored by studying the shell-structure unique in weakly-bound neutrons for spherical or deformed shape. It is pointed out that due to the narrowed N=50 spherical energy-gap and a few resulting close-lying neutron one-particle levels, 1g$_{9/2}$, 3s$_{1/2}$, and 2d$_{5/2}$, for spherical shape, nuclei with some weakly-bound neutrons filling in those levels may be deformed and have a good chance to show deformed s-wave halo. Promising candidates are $^{71}_{24}$Cr$_{47}$, $^{73}_{24}$Cr$_{49}$, $^{75}_{24}$Cr$_{51}$ and $^{77}_{26}$Fe$_{51}$ in the case that those nuclei lie inside the neutron drip-line. An interesting possibility of the deformed p-wave or s-wave halo is suggested also for the nucleus $^{53}_{18}$Ar$_{35}$.
