Inelastic collisions of moderate energy electrons with molecular ions generally induce excitation and ionization reactions, which mainly result in the dissociation of the target.
Experimental studies are performed in a crossed electron ion beams set up. A particular attention is carried in careful identifying the various concerned processes, and in the kinetic energy analysis of the dissociation products.
The concerned ions are essentially those ions which play a role in atmospheric or thermonuclear plasmas. For example, they are atmospheric ions (H2+, N2+, O2+, CO+, CO2+, ...), hydro(deutero)carbons ions belonging to the methane and the ethane families (CmHn+ or CmDn+) as well as XH+ or XD+ ions where X stands for Be, C, N, O and for rare gases (He, Ne, Ar, Kr) frequently introduced in tokamaks.
