摘　　要：充分考虑电子间关联效应,利用多组态相互作用方法构造了Ga^(28+)离子1s^(2)nl(l=0,1,n=2~9)Rydberg态的波函数.在此基础上,计算了Ga^(28+)离子1s^(2) nl(l=0,1,n=2~9)Rydberg态的特殊质量移位.为了进一步检验波函数的可靠性和准确性,还计算了Ga^(28+)离子等电子序列(Z=31~40)1s^(2)2s态的特殊质量移位.通过本文的计算可知,特殊质量移位的数量级和能级超精细结构的数量级相当,其计算精度主要依赖于体系波函数的关联效应,计算得到的特殊质量移位符合等电子序列的变化规律.The wavefunctions of 1s^(2)nl(l=0,1,n=2~9)Rydberg states for the Ga^(28+) ion are constructed by using the multi-configuration method with careful consideration of electronic correlations.Then the specific mass shifts of the 1s^(2)nl(l=0,1,n=2~9)Rydberg states for the Ga^(28+) ion are calculated with the wavefunction.In order to testify the veracity of wavefunction,the specific mass shifts of 1s^(2)2s along iso-electronic sequence from Z=31 to 40 are calculated.According to the results obtained in this paper,the precision of the specific mass shift is sensitive to the correlation described by the wavefunction,and its magnitude is comparable to the hyper-fine structure.These calculation results follow the rule of the iso-electronic sequence well.
