Abstract
We have calculated the forbidden transition energies and magnetic dipole tr ansition probabilities of 2s(2)2p(4)(P-3(1)-P-3(2)) and 2s(2)2p(4)(P-3(0)-P -3(1)) of oxygen-like isoelectronic sequences (Z=10-32) by a method of pola rization potential correction. The transition energies show good agreement with experiment and are much better than the calculations in the literature . These results also illustrate that it is feasible to use the dipole expan sion of the polarization potential to deal with some dynamic and non-dynami c effects in the central field approach. The relation of polarizability and cut-off radius with atomic number is discussed. We also give the fitted fo rmula between the polarizability al and atomic number Z as alpha (1)=0.7342 9-9.56644x10(-4)Z+7.43016x10(-5)Z(2)-2.53298x10(-6)Z(3)+2.08306x10(-8)Z(4).
