In near adiabatic collisions of bare to He-like Xe ions with Xe atoms multi-electron transfer processes are studied by measuring the emitted target- and projectile K- and L- x rays in coincidence with projectiles which have captured 3 to 6 electrons, and with time of flight of recoiling Xe target ions. We find that in the projectiles a wide range of electron levels even with main quantum numbers n>5 are excited- extending to a very significant population of Rydberg levels, all dependent on capture multiplicity; a strong contribution of K x rays from high n shells indicates that outer shell transfer avoids Yrast states l=n-1 but dominantly prefers low l states of the projectile with l=1.
