The electronic capture is pictured as a tunnelling process in a model potential. This allows to analytically compute the transmission probability. Some comparisons with data from existing literature are given.RevTex 4, 3 EPS figs., 5 pagesAtomic PhysicsAn easy method to estimate charge-exchange cross sections between ions and one-active-electron atomstext
