摘要
用全实加关联方法计算了类锂离子(Z=11～20)激发态1s2nf(n=6,7,8)的能级和精细结构劈裂,并计算了偶极跃迁1s23d-1s2nf(n=6,7,8)的跃迁能和振子强度.非相对论能量用Rayleigh Ritz变分法确定,相对论修正和质量极化效应用微扰论计算,还估算了来自量子电动力学效应的修正.
The transition energies 1s^23d-1s^2nf(n=6,7,8) of lithium-like systems with nuclear charge from Z =11 to 20 are calculated by using a full-core plus correlation (FCPC)method. The non-relativistic energies and wave functions are calculated by Rayleigh-Ritz's variation method. Relativistic and mass-polarization effects on the energies are included as the first-order perturbation corrections. The quantum-electrodynamical contributions to the transition energie are also evaluated by using effective nuclear charge. The dipole oscillator strength 1s^23d-1s^2nf(n=6,7,8) of these ions are calculated by using our FCPC wave functions.
