中文摘要：
基于相对论多组态Dirac—Fock方法（MCDF方法），详细研究了Xe及类Xe离子的束缚和连续的f轨道波函数的性态，分析了沿等核系列和等电子系列f轨道径向波函数的塌缩现象．在此基础上，进一步讨论了轨道波函数的塌缩导致的强弛豫效应及其对类Xe离子的4d^10-^4d^94f跃迁能和振子强度的影响．
英文摘要：
Bound and continuous f-wavefunctions of ions along xenon isonuclear and isoelectronic sequences have been calculated using the multi-configuration Dirac-Fock method. As a result, the collapse behaviours of the f-wavefunction have been studied systematically. Furthermore, the transition energies and oscillator strengthes of 4d^94f-4d ^10 transition for xenon-like ions have been presented and discussed by comparing with some exising experimental and theoretical results. A huge enhancement of the oscillator strengthes caused by the collapse effects has been found in the ions with Z≥56.
