摘要

本論文以MCRRPA理論探討類鈹碳離子在(1s1/2 2 2s1/2)2S1/2 o和(1s1/2 2 2p3/2)2P1/2 o 兩離閾間的光離過程。在此能量範圍的光電子能譜呈現 (2pns)1P1o、(2pns)3P1o、(2pnd)1P1o、(2pnd)3P1o 和(2pnd)3D1o 等五個瑞德伯系列的自離共振結構。我們計算此五個雙激共振系列的光離截面、光電子角佈與極化參數，以及其與共振能和共振寬的關係，以提供未來的理論與實驗作參考。

We have investigated photoionization of the C2+ ion by using the multiconfiguration relativistic random-phase approximation theory. Precise energies and widths of all five Rydberg series of doubly-excited states (2pns)3,1P1o , (2pnd)3,1P1o , and (2pnd)3D1o are given in the photon-energy region between (1s2 2s)2S1/2 and (1s2 2p)2P1/2 ionization thresholds. Comparisons with previous theoretical works and experimental measurements are also made.
