摘要/Abstract

摘要： We have calculated the forbidden transition energies and magnetic dipole transition probabilities of 2s²2p⁴(³P₁－³P₂) and 2s²2p⁴ (³P₀－³P₁) of oxygen-like isoelectronic sequences (Z=10－32) by a method of polarization 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 expansion of the polarization potential to deal with some dynamic and non-dynamic effects in the central field approach. The relation of polarizability and cut-off radius with atomic number is discussed. We also give the fitted formula between the polarizability α₁ and atomic number Z as α₁=0.73429-9.56644×10^-4Z+7.43016×10^-5Z^{2-2.53298×10^-6Z^{3+2.08306×10^-8Z⁴.}}

These results also illustrate that it is feasible to use the dipole expansion of the polarization potential to deal with some dynamic and non-dynamic effects in the central field approach. The relation of polarizability and cut-off radius with atomic number is discussed. We also give the fitted formula between the polarizability $\alpha_1$ and atomic number Z as $\alpha_1$ = 0.73429-9.56644×10^-4Z+7.43016×10^-5Z²-2.53298×10^-6Z³+2.08306×10^-8Z⁴.
