Ar8+-C-60 collisions at v = 0.4 au electron capture and target fragmentation

We report experiments concerning collisions of slow Ar8+ ions on a gaseous C-60 target. We measured recoil ion mass spectra in coincidence with the final charge state analysed projectiles Ar7+, Ar6+, Ar5+ and Ar4+ successively and we were able to establish correlation between low energy fragments produced by break up of molecular C-60(r+) ions. We also measured the relative cross sections of multicaptured processes, especially the stabilization ratio of two electrons in double capture process which has been found R-s(2) = 5%. The r-electron capture cross sections for r = 1-5 are compared with predictions of the C.B.M. barrier model.
