摘要
基于多组态Dirac-Fock方法对类C离子AlⅧ的能级结构以及跃迁参数进行计算.Breit修正和QED修正以及核的有效体积效应和核的质量修正等效应加入到体系的哈密顿量,作为能级和波函数的高阶修正.与实验值和其他计算的理论值做了比较.分析计算结果,计算基态和激发态的能级等数据与实验值和其他理论值符合得比较好.计算的数据弥补了光谱数据的不足,为以后研究AlⅧ的实验奠定了理论基础.
Based on the multi-configuration Dirac-Fock method,the energy and transition parameters of C-like Al were calculated.Breit and QED correction as well as the effective volume effect of the nucleus and the nuclear mass correction effects were added to the Hamiltonian.The calculated data are in good agreement with the experimental values and other theoretical values.The calculated data compensate for the lack of spectral data and provide a theoretical basis for future researchers experiments on AlⅧ.
