Absolute charge-exchange cross sections for the interaction between slow Xe{sup q+} (15{le}q{le}43) projectiles and neutral He, Ar, and Xe
- Department of Atomic Physics, Stockholm University, Frescativaegen 24, S-104 05 Stockholm (Sweden)
We report measurements of absolute cross sections for single- and multiple-electron capture in slow collisions (v{approximately}0.1{endash}0.2a.u.). Partial cross sections for simultaneous r-electron removal from the target and p- electron retainment by the projectile {sigma}{sub q,q{minus}p}{sup r} are presented for the systems Xe{sup q+}-B, B=He, Ar, and Xe (15{le}q{le}43). The results are also described in terms of electron-retainment ({sigma}{sub q,q{minus}p}), electron-removal ({sigma}{sub q}{sup r}), and total-reaction ({sigma}{sub q}) cross sections. Further, we deduce experimental single-electron-capture cross sections {sigma}{sub q{minus}1,q{minus}2}{sup 1} for Xe{sup (q{minus}1)+}-B collisions from measurements on the Xe{sup q+}-B system. The data are compared with earlier and more recent scaling laws and the extended classical over-the-barrier model. {copyright} {ital 1997} {ital The American Physical Society}
