I. M. Savukov, W. R. Johnson

摘要:

在V(N-2)Hartree-Fock势下,用多体微扰理论(MBPT)对双价原子组态相互作用(CI)进行了修正.描述了混合CI+MBPT理论的两个变体,并应用于获得Be、Mg、Ca和Sr的能级和跃迁振幅。

英文摘要:

Configuration interaction (CI) calculations in atoms with two valence electrons, carried out in the V(N-2) Hartree-Fock potential of the core, are corrected for core-valence interactions using many-body perturbation theory (MBPT). Two variants of the mixed CI+MBPT theory are described and applied to obtain energy levels and transition amplitudes for Be, Mg, Ca, and Sr.
