高离化态Au离子光电离过程的理论研究

Theoretical Studies on Photoionization Processes ofHighly Charged Au Ions

    摘要
  • 摘要: 基于多组态Dirac-Fock方法的程序包GRASP92和RATIP及在此基础上最新发展的RELPHOTO08程序， 系统地研究了高离化态金离子M壳层的光电离截面随入射光子能量、 离化度以及壳层的变化规律。结果表明： 光电离截面随光子能量的增大而单调减小； 电离nl电子时， 如果相关电子的主量子数较大， 则该电子存在与否对其光电离截面几乎没有影响； 在同一离化度下， 角量子数l可引起两种性质不同的效应， 其相互竞争可导致光电离截面随入射光子能量的复杂变化。Based on multiconfiguration DiracFock method and the corresponding packages GRASP92 and RATIP, as well as the newly developed RELPHOTO08, the variations of M subshell photoionization cross sections with the photon energy, ionization degree and subshells for highly charged gold ions are studied systemically. The present results show that the cross sections are decreasing monotonously with the photon energy; for the photoionization of nl electrons, if the principal quantum number of removed electron is large enough, the cross sections are essentially unchanged upon the presence or absence of outer electrons; for same ionization degree, the angular quantum number introduces two opposite effects which could exist simultaneously, and the intricate variations of cross sections with the photon energy originate from the competition between these two different effects.
