Resonant electron transfer andL-shell excitation at 3.6 MeV/u62Sm q+ → Xe collisions,q=34−52

For 3.6 MeV/u Sm ^q+ projectiles a hump in the projectile (L _l +L _α) x-ray emission cross section is seen as a function of charge stateq for highq with 46≦q≦52 (closed incomingL shell). This hump is attributed to the Resonant electron Transfer from the Xe target atom with simultaneous Excitation of anL ₃-shell electron to theM shell. The cross section for thisL ₃-shell RTE process has values up to 2·10^?19 cm², which is seen in single spectra already. To verify the existence of theL-shell RTE process for the studied collision system, extensive calculations have been carried out. Especially theL ₃-shell fluorescence yield for the radiative stabilization process in the highly-charged projectile has been considered. Our calculatedq-dependent cross sections for the RTE process support the given interpretation.
