摘　　要：采用全相对论量子力学GRASP2程序,广义平均能级EAL模型,在核的有限体积效应,Breit和QED效应的高阶扰动基础上,考虑到原子实的极化,系统地计算了高剥离类钾离子4s2S1/2─3d2D3/2电四极矩E2光谱跃迁的能级间隔,跃迁概率和振子强度,结果表明:考虑原子实极化效应后,计算的精细能级结构间隔与实验数据之间的系统误差基本消除,其跃迁概率和振子强度属首次报道.A fully relativistic muhiconfiguration Dirac-Fock method with Breit and QED corrections is used to calculate the 4s 2^S-3d2^ D（ Z = 22-42）transition energy level separations, transition probabilities and oscillator strengths for the K-like ions. In the calculation, we have considered the significant Breit and QED corrections. The results are in good agreements with recent experimental data and other theoretical values. The results show that the electric quadrupole transition probabilities are in correspondence with these of E1 transitions and can not be ignored in the laser plasma of high temperature in ICF and MCF Fusion.
