 We have theoretically investigated charge exchange processes occurring at low collisions of Rb atoms with Ca and Yb cations based on quantum-chemical accurate data for adiabatic potential energy curves and coupling matrix elements. The calculated cross sections exhibit all features of the Langevin ion-atom collision regime including a rich structure associated with centrifugal barrier tunneling (orbiting) resonances. We have shown that in contrast to Ca+ + Rb collisions the dominant process in Yb+ + Rb
collisions is the radiative charge transfer
