Popis:	The total charge-transfer cross sections in Sr++Mg and Sr++Ca collisions are investigated experimentally using the crossed-beam technique in the energy range 250-1300 eV. The theoretical two-state calculations are performed by numerical solution of the Schrodinger equation. A considerable underestimation of the experimental data is found and discussed. It is concluded that the simple theoretical models used relatively successfully for alkali-ion-alkali-atom systems, are not adequate for alkaline-earth-ion-alkaline-earth-atom systems.
