K-,L-, M- IONIZATION OF Cu AND Ge IN COLLISIONS WITH 0.25 -2.5 MeV/u 32S IONS C. Ciortea, D. Dumitriu, A.Enulescu, D. Fluerasu, I.Piticu and Z. Szilagyi Tandem Laboratory, Horia Hulubei National Institute for Physics and Nuclear Engineering, P.O. Box MG-6, Bucharest, Romania K-shell ionization cross sections and mean ionization probabilities per electron of the L- and M- shell of Cu and Ge in collision with 0.25-2.5MeV/u 32S ions are reported. The experimental data have been interpreted in terms of the semiclassical approximation
