类铷W37+离子双电子复合速率系数的理论研究
Theoretical study on dielectronic recombination rate coefficient of Rb-like W37+ ions
摘要
Abstract
Calculations of dielectronic recombination(DR) rate coefficients from the ground state 3s2 3p6 3d10 4s2 4p6 4d of Rblike W37+ ions through doubly excited states (3s2 3p6 3d10 4s2 4p6 4d)-1 nln'l' (n, n' = 4,5) are performed using the fully relativistic configuration interaction method. Total DR rate coefficients are obtained in the temperature range from 1 to 5 × 104 eV. Comparison of the DR rate coefficients from different subshell excitations shows that 4p subshell excitation dominates at low temperature,while 3d subshell excitation dominates at high temperature. The two-electron and one-photon radiative transitions are found to be important due to the strong configuration interactions, and the radiative transition 4p5 4d5 d5f-4p64f5d contributes more than 5 % of the total DR rate coefficients through the doubly excited state 4p5 4d5d5f. The total DR rate coefficients are greater than the radiative recombination(RR) and three-body recombination(TBR) rate coefficients for the whole energy region.关键词
