title = "Single and double K -shell vacancy production in slow Xe54+,53+ -Xe collisions",
abstract = "We present an experimental and theoretical study of symmetric Xe54+ + Xe collisions at 50, 30, and 15 MeV/u, corresponding to strong perturbations with vK /vp = 1.20, 1.55, and 2.20, respectively (vK is the classical K-shell orbital velocity and vp is the projectile velocity), as well as Xe53+ + Xe collisions at 15 MeV/u. For each of these systems, x-ray spectra are measured under a forward angle of 35◦ with respect to the projectile beam. Target satellite and hypersatellite radiation Kαs 2,1 and Kαhs 2,1, respectively, are analyzed and used to derive cross-section ratios for double-to-single target K-shell vacancy production. We compare our experimental results to relativistic time-dependent two-center calculations.",
