Selfhyphen;Consistent Calculation of Dynamic Polarizability and Excitedphyphen;State Wavefunctions of Twohyphen;Electron Atom and Ions

摘要

Dynamic polarizability of He and isoelectronic ions has been calculated by a selfhyphen;consistent variationndash;perturbation method. An interpolation relation has been obtained which may be used to estimate the polarizability of ions in actual crystals under the influence of a radiation field. Representations of excitedpstates have been obtained. They compare favorably with more accurate calculations available. The advantage of the present method lies in its simplicity. It can be easily extended to atoms containing many electrons.
