摘要：

The multiple ionization and fragmentation of N-2 in collisions with fast H+ He+, Bi25+, and Bi57+ ions was studied using a position- and time-sensitive multi-particle detector. By the coincident measurement of correlated fragment moments a kinematically complete image of the fragmentation process can be obtained for each individual event. Of special interest are the "Coulomb explosion" processes N-2-->Nq++Np+ where the dissociation energy and the ionization cross section as a function of the orientation of the molecular axis can be derived.
