摘　　要：在相对论平均场框架内结合NL-SH和TM1/TM2参数计算和讨论了质量数在A=35~47区间,Ar质子能级反转对Ar-K同位旋相似态库伦移动能的影响。计算分为考虑Ar丰中子同位素的2s_(1/2)和1d_(3/2)质子能级反转和不考虑Ar丰中子同位素的2s_(1/2)和1d_(3/2)质子能级反转2种情况。计算结果显示:Ar的2s_(1/2)和1d_(3/2)质子能级反转可能会导致Ar-K同位旋相似态库伦移动能降低0.06 MeV^0.17 MeV。该结果既可以为实验上研究原子核核子能级反转提供参考,也可以为相对论平均场模型提供新的检验。Effects of Ar proton level inversion on the Coulomb displacement energies of the neutron-rich Ar-K isobaric analog state pairs with mass number A = 35～47 are calculated and discussed within the relativistic mean field frame. The calculations are carried out in two cases ： with and without consideration of the possible 2s1/2 and 1d3/2 proton level inversion of the neutron-rich Ar isotopes. Results show that the 2s1/2 and ld3/2 proton level inversion of the neutron- rich Ar isotopes may reduce the Coulomb displacement energies of Ar-K isobaric analog states by 0.06 MeV-0.17 MeV. The results may provide a reference for experimental investigations of nuclear level inversion, and a new test for the relativistic mean field model as well.
