The effects of quantum interference between direct and resonant photorecombination of H-like Ar¹⁷⁺ions

Abstract

The multiconfiguration Dirac-Fock method has been used to study interference effects between direct and resonant photorecombination (i.e. radiative and dielectronic recombination) from the ground state 1s 2 S 1/2 of H-like Ar 17+ ions via doubly excited 2s 2

State‐selected photo‐recombination cross sections of H‐like ions in the KLL resonant energy range

“…However, most of these works have not taken into account the quantum interference between these two processes. To incorporate the interference effects in the study of the PR processes, Wan et al [19] introduced Fano parameters and based on the Fano method. The results shown an asymmetry profiles in the theoretical calculated PR cross sections.…”

Theoretical study on photorecombination of C V ion

“…The advantage of nonperturbative approach is that it automatically includes any quantum-mechanical interference between the resonant part (DR) and the nonresonant part (RR), the drawback is that it normally omits radiation damping. Although radiation damping is easily included by perturbative approach, [4][5][6] it is impracticable to include all the perturbative orders in practical calculations. In view of the above, nonperturbative approaches, such as the close-coupling R-matrix theories of Burke, Hibbert, and Robb, [7,8] are used in the present paper.…”
