Abstract

For 3.6 MeV/u Smq+ 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.
