自电离序列间的相互作用

INTERACTIONS OF AUTOIONIZING SERIES DAI CHANG-JIAN Department of Physics

本文采用多通道量子数亏损理论对Ｍｇ原子的Ｊ＝３．３ｐｎｄ自电离Ｋｙｄｂｅｒｇ序列间的相互作用进行了分析，研究了通道相互作用对于自电离态的线形，自电离速率的影响。考察了在电离限附近原子的特性以及在其两侧电子的波函数的连续性，获得了与实验相一致的自电离光谱。

The interseries interaction of the Mg 3ped J=3 autoionizing Rydberg series hasbeen studied using muItichannel quantum-defect theory.Its impact on the excitationprofiles and the autoionization rates has been investigated.The bebaviors of the Mgatom and the continuity of the electron's wavefunction near the ionization thresholdare examined.The agreethent between the calculatcd antoionizing spectra and thecxperimental ones is found to be satisfactory.
