摘要:在Dirac-Slater相对论理论框架下,研究了HCI(高离化态离子)的基本性质及其光电离过程的基本特征.通常HCI的电场非常强,其电子波函数沿靠近核的径向空间被压缩,这极大地改变了相应的物质的性质,使HCI的光电离过程与一般的原子(离子)的相比较有很大的不同:原子核的尺寸效应和相对论效应变得更加重要,而多极效应对光电离截面的影响却趋于减弱.
By using the Dirac-Slater relativistic average self-consistent theory ,the fundamental properties of HCIs ( highly charged ions ) and the corresponding photoionization processes have been studied .HCIs provide the stron-gest static field available in any laboratory ,the compression of wave functions into the space near the nucleus is so strong even for the outer electrons of heavy ions that it dramatically alters the relative importance of various physi -cal effects that determine the atomic structure .All these indicate that the influence of the nuclear finite-size effects and relativistic effects on photoionization cross sections is very important for HCIs ,but the multipole effect on photoionization cross section turns to feeble .
