Fragmentation and mean kinetic energy release of the nitrogen molecule

Ionization and fragmentation of the N2 molecule in coincidence with the final projectile charge state have been measured for the impact of 0.188–0.875 MeV/amu He+ projectiles. The average kinetic energy release (KER) of the target ionic fragments is derived from the peak widths of their time-of-flight distributions. It is shown that the KER’s for singly-charged products follow scaling laws irrespectively to the collision channel.
