Predissociation

Laser photofragment spectroscopy has a close analogy with atom-ion scattering [73] and thus shares much of the same terminology. Indeed, the fragmentation process can be considered as the second half of a full collision, with exact controls over input energy. The term `resonance' is often used to describe levels which are quasibound with respect to the continua of the separated atoms. Three mechanisms by which resonances may arise are considered here:
