State-selective scattering angular dependent fragmentation of N2 by slow Kr8+ ion impact

We have newly developed a multiple coincidence method to study state-selective scattering angular resolved fragmentation of molecules caused by slow highly charged ion impact. The fragmentation of N2 in double charge changing collisions of Kr8+ at 19 eV/u has been investigated using the multiple coincidence technique. The energy gain distributions and scattering angle distributions of product Kr6+ ions in coincidence with the double time-of-flight of fragment ions are obtained for fragmentation processes of N++N+ ions, N++N2+ ions and N2++N2+ ions, and the reaction energies of their processes are determined
