Dissociation and fragmentation of N2 molecules by slow highly charged ions

Single and multiple electron capture processes are investigated in slow collisions between highly charged Xeq+ (q = 15-21) ions and molecular nitrogen. The formation of N2q+ ions by electron capture, dissociation of molecular ion N2+ and Coulomb Explosion of N2q+ (1 < q ⩽ 5) were observed. Various dissociation and Coulomb explosion (CE) channels related to multiple electron capture can be identified in the two-dimensional plot. The kinetic energy release of the fragments is derived from the time-of-flight spectra. The results are compared with CE model.
