摘要
基于Dirac-Slater相对论平均自洽场理论和类氢模型,研究了自由电子被辐射复合到裸核和类裸核离子的n壳层时RR截面随自由电子能量的变化,以及原子实对这种变化的影响;给出了两种理论模型下RR截面曲线变化的差异,并对这种差异做了较详细的理论说明.
Based on a single-electron Dirac-Slater relativistic average self-consistent field and hydrogen-like model,The variation of RR(radiative recombination) cross section with electron energy when free electron captured into n orbitals of bare ions and bare-like ions have been studied systemically,as well as the effects of atomic core on the variational character. Finally the difference of variation for RR cross section within relativistic self-consistent field and hydrogenlike model, and the theoretical explain of the difference are given.
