• 中文摘要： 本文中回顧一個簡單非變分式之組態交互作用理論。對在 閉殼層外具有兩個電子之二價原子系統，諸如各鹼土原子及其對應之等電子序列，此項理論可用以探討各種取決於電子關聯的原子特性。文中詳述相關理論細節，計包括有多組態狀態波函數及其對應之能量本徵值、振子強度及束縛態之間的原子躍遷機率、激發態之幅射壽命、雙重激發自電離態之共振能及寬度、雙重激發自電離態為主之光致電離、及與自旋有關之磁交 作用所導致之精細結構能階分裂。此外，並特別討論了一套用B-spline所建立之近乎完全之 -也有限基組的使用，而可有效地顧及受制於有限體積內之正能量單電子軌域，對連續區所具有的貢獻。
• 英文摘要： A simple non-variational configuration-interaction approach for various atomic properties dominatedby electron-electron correlation in a divalent atomic svstem with two electrons outside a closed shell core, such as an alkaline earth atom and its corresponding isoelectronic sequence, will be reviewed.We present in detail the theoretical procedures for the multiconfiguration state wave function and its cor-responding energy eigenvalue, the oscillator strengths and the transition probabilities for bound-boundatomic transitions, the radiative lifetimes of the excited states, the resonance energy and the width of thedoubly excited autoionization states, the photoionization dominated by the doubly excited autoionizationstates, and the fine-structure-level splittings due to spindenendent maenetic interactions. In particular.we will discuss the use of a nearly complete G'-finite basis set constructed from B splines which is capableof taking into account effectively the continuum contribution from positive-energy one-electron orbitalsconfined in a finite volume.
