Energy structure of the 1s^(2)n p(2≤n≤9)Rydberg configuration for Ga^(28+)ion

利用全实加关联方法构造了Ga^(28+)离子1s^(2)np(2≤n≤9)Rydberg态的波函数,通过Rayleigh-Ritz变分法计算了1s^(2)np Rydberg态的非相对论能级.在此基础上,充分考虑一阶相对论效应、质量极化效应、高阶相对论效应和量子电动力学效应对能级的影响,计算了Ga^(28+)离子1s^(2)np(2≤n≤9)Rydberg态的精细结构劈裂、激发能和电离能.得到的精细结构劈裂符合Rydberg态的变化规律,激发能和电离能结果与现有实验数据也符合得很好,具有较好的精度.

The wavefunctions of the 1s^(2)n p(2≤n≤9)Rydberg configuration for Ga^(28+)ion are constructed with the full-core plus correlation method.The non-relativistic energies of the 1s^(2)n p(2≤n≤9)states for Ga^(28+)ion are calculated with the Rayleigh-Ritz method.The fine structure splitting,the excited energy and ionization energy are obtained with the thoughtful considerations of the first-order relativistic effect,the mass-polarization effect,the higher-order relativistic effect and quantum-electrodynamics correction.It is satisfing to find the fine structure splitting calculated follows the regularity of the Rydberg configuration.The results calculated in this paper closely agree with the experimental data available in literature,which proves the accuracy and reliability of the method adopted in this work.
