Theoretical study on dielectronic recombination rate coefficient of Rb-like W³⁷⁺ ions

Calculations of dielectronic recombination(DR) rate coefficients from the ground state 3s23p63d104s24p64d of Rb-like W37+ ions through doubly excited states (3s23p63d104s24p64d))-1nln′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 stro
