Ti21＋和Ti20＋离子双电子复合过程的理论研究
T heoretical study on dielectronic recombination of highly charged Ti21+ and Ti20+ ions
摘要
Abstract
In this work , the KLL dielectronic recombination(DR) processes and linear polarization degree of emitted X‐rays are investigated for Ti21+ (1s ) and Ti20+ (1s2 ) ions in the framework of multi‐configuration Dirac‐Fock(MCDF) method and the density matrix theory . The resonance energis , radiative and Aauger transition probabilities , the resonance strengths , angular distributions and linear polarization degrees for all of KLL dielectronic satellite lines are presented . In the calculations , the electron correlation effects , QED effects and Breit interactions have been well considered . Comparison is made between the present results and the EBIT experimental measurements ,a good agreement is obtained .关键词
