Research Abstract

When a molecule is excited at the inner-shell level, specific reactions are often observed such as bond fissions around the atomic site of excitation. The purpose of this study is, for some gaseous molecules, to establish the fragmentation processes by a measurement technique discriminating between the fast process of specific fissions and the relatively slow dissociation channel(s) following the energy relaxation. In particular, identification of the fragment ions and their formation and dissociation behavior are studied by a double fragment coincidence method.
