Fragmentation of N2 and post collision effects in slow electron capture collisions of Kr8+ ion below 200 eV/amu

The fragmentation of molecular ions produced in collisions of Kr8+ ion with N-2 has been studied at low energies below 200eV/amu by a double-coincidence TOF technique. All processes taking place in single-, double-, and triple-charge changing collisions were identified and their branching ratios were measured. The distributions of kinetic energy released in fragmentation of molecular ions were also determined. New phenomena of molecular ion peak splitting and a first experimental evidence for the oriented fragmentation occurring have been observed.
