摘要: We report experiments concerning collisions of slow Ar8+ ions on a gaseous C60 target. measured recoil ion mass spectra in coincidence with the final charge state analysed projectiles Ar7+, Ar6+, Ar5+ and Ar4+ successively we were able to establish correlation between low energy fragments produced by break up molecular C60r+ ions. also relative cross sections multicaptured processes, especially stabilization ratio two electrons double capture process which has been found Rs2 = 5%. The r-electron for r 1-5 are compared predictions C.B.M. barrier model.
