^(69)Ni、^(70)Ni激发态的相对论平均场研究

Study the excited states of ^(69,70)Ni with relativistic mean field theory

在球形相对论平均场模型下,采用NL3相互作用,对69N i、70N i基态以及第一、第二激发态进行计算.从核子的半径、价核子的激发能以及中子和质子的密度分布,得出结论:在69N i7、0N i第一和第二激发态都可能存在中子晕现象.

Properties of the ground spherial relativistic mean - field theory states and low - lying excited states of nuclei ^69,70Ni are with NL3 force parameter. By analyzing the rms radii investigated in of proton and neutron, the single particle energies of valence nuclei and the density distributions of proton and neutron, the halo structures are suggested in the first excited states or the second excited states of ^69,70Ni.
