In the first Born approximation the ionisation probabilities of the ns states (n=1 and 2) of hydrogen-like ions by nuclei corresponding to the transitions with the different changes in the orbital angular momentum projection of the relative motion h(cross) mu have been calculated at a fixed impact parameter rho . It has been shown within the 5% accuracy that the total ionisation probability and cross section are determined by the transitions with mod mu mod <or=2 n.
