An experimental investigation of resonant transfer and excitation (RTE) for collisions of Mg9+ (lithiumlike) projectile ions with a molecular hydrogen gas target has been made. The experimental cross sections for projectile K-shell x rays coincident with electron capture in the energy of 33- to 60-MeV are found to be in good agreement with theoretical RTE calculations. The present results confirm the agreement between experiment and theory which has been reported for RTE involving K-shell excitation for projectiles with atomic numbers between 9 and 92 incident on H2 and He targets.

Cross sections for total K-shell x-ray production and K-shell x rays coincident with electron loss as well as total single-electron-capture and total single-electron-loss were also measured for 33- to 60-MeV Mg9+ + H2 collisions .
