丰中子轻核新幻数N=16的解释(英文)

Explanation on New Magic Number N=16 in Light Neutron-rich Nuclei

基于中子分离能的分析 ,Ozawa等提出丰中子轻核存在新幻数 N=1 6 .对 N=1 6同中子素进行了形变和球形的相对论平均场计算 .相对论平均场的数值结果表明 N=1 6同中子素有形状相变 .这是一些丰中子核新幻数出现的可能原因 .

Based on the analysis of neutron-separation energies, Ozawa et al proposed a new magic number N =16 in light neutron-rich nuclei. The deformed and spherical relativistic mean-field(RMF) calculations have been carried out for N =16 isotones. The numerical relativistic mean-field results show there is a shape transition in N =16 isotones. This is the possible cause of the appearance of the new magic number in someneutron-rich nuclei.
