The evaporation model developed by Russek and collaborators for multiple ionization of outer-shell electrons in ion-atom collisions has been applied to the charge distribution of the daughter atom produced by α decay of 210Po. The calculated result indicates that most of the daughter atoms are positively charged ions with a mean charge of + 1.41. The other ionization mechanisms, the recoil effect and the shake-off effect, are also considered. In comparison with the recent experimental results, it is shown that the evaporation model predicts more adequately than the recoil effect and the shake-off effect.
