- Electron transfer between a neutral target and a projectile ion is one of the more interesting and difficult processes to calculate. Experimentally, there is no simple, yet clean, way to measure transfer from a given shell to a given shell. For the case of K to anti K transfer (the bar designating the projectile) an indirect method is common. One measures K-vacancy cross sections for projectiles with ionic charges q = Z, Z-1, and less than or equal to (Z-2). Then with the assumption that the initial anti K electrons are inert, one infers the K/sup 1/ to anti K/sup 1/ and K/sup 2/ to anti K/sup 2/ cross sections from linear combinations of the measured cross sections. The postulate that anti K-electrons are inert is brought into doubt by noting that the probability of inverse (anti K to K) transfer is equal by time-reversal invariance to that for K to anti K transfer. An extensive set of such measurements has been reported recently by J. Hall for the nearly symmetric, strongly interacting systems /sub 17/Cl/sup q+/ + /sub 22/Ti. We have performed coupled-channels calculations for these systems and have compared results of various forms of the independent Fermi particle model (IFPM) with and without the assumption that any initially present anti K electron is passive. The passive anti K-electron models provide only a fair approximation to the results of the full IFPM. 5 refs., 4 figs.
