摘　　要：用全实加关联方法计算了Sc18+离子1s22s和1s22p态的非相对论能量.在计算相对论效应和质量极化效应对体系能量的一级修正的基础上,通过引入价电子的有效核电荷,在类氢近似下,估算了QED和高阶相对论效应对能量的修正,计算了该离子1s22s-1s22p的跃迁能、波长、在3种规范下的振子强度以及1s22p态的精细结构.得到与现有实验数据符合得很好的结果.By means of full-core plus correlation method the non-relativistic energies of 1s^2 2s and 1s^2 2p states for Sc^18＋ ion are calculated. Basing on calculating the first-order corrections to the energy from relativistic and mass-polarization effects, we estimate the higher-order relativistic contribution and QED correction to the energy under a hydrogenic approximation. The transition energies, wave-lengths, oscillator strength for the 1s^2 2s-1s^2 2p transition and fine-structure splitting of 1s^2 2p state for this ion are calculated. The results agree with available experimental data satisfactorily.
