Abstract:

The relativistic configuration interaction method is employed to investigate the resonant transfer excitation (RTE) processes of Kr34+ colliding with CH4, NH3, H2O, and HF targets under the impulse approximation. Compared to the case of CH4, the RTE cross sections of NH3, H2O, and HF targets reduce by 10.7%, 23.3%, and 33.6% in the first peak position and by 6.0%, 12.3%, and 18.9% in the second peak position, respectively, due to the decrease in Compton profiles in the small momentum region. On the other hand, the width of the peaks increases from CH4 to HF, which indicates that strong Coulomb effect leads to the broader momentum distribution.

Key words: dielectronic recombination, resonant transfer excitation, Compton profile
