Resonant Transfer Excitation of Fluorine-Like Mo33+ Ion

Abstract

Dielectronic recombination (DR) cross sections (σDR) and rate coefficients (αDR) for Mo33+ are calculated using the angular momentum average scheme (AMA). Moreover, the resonant transfer excitation followed by X-ray emission (RTEX) cross sections (σ RTEX) for the collision of Mo33+ with H2 and He targets are calculated and studied. The calculations of the cross sections are performed for both K- and L-shell excitations. A smooth change with the temperatures for αDR is found for all kinds of excitations. The rates for K-shell excitation are very small in comparison with the rates for Lshell excitation. The RTEX cross sections for Mo33+ ions are obtained from their corresponding DR cross sections by the method of folding in the impulse approximation (IMA). σ RTEX for the K-shell excitation shows two overlapped peaks which may be attributed to the two groups in this excitation process. The present calculations are considered as a database for future comparison with theoretical and experimental data using other coupling schemes. Multiple Auger channels are complicating the dependence of the cross sections on principal quantum numbers.
