INELASTIC PROCESSES IN 1-1000 KEV U COLLISIONS OF BE-Q+ (Q=2-4) IONS WITH ATOMIC AND MOLECULAR-HYDROGEN/

Owing to the use of beryllium in fusion reactors and the consequent ne ed to model and diagnose plasmas containing this species of impurity, cross sections are presented here for inelastic collisions of 1-1000 k eV/u Be-q+ (q=2-4) with H and H-2. In particular, the classical trajec tory Monte Carlo technique is used to compute total cross sections for (i) ionization, (ii) state-selective excitation, and (iii) state-sele ctive charge transfer.
