A fully relativistic multiconfiguration Dirac-Fock method with Breit and QED corrections is used to calculate the 4s 2S─3d 2D(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.
