Abstract
A two-state approximation based on atomic wavefunctions is used to calculate cross sections for electron capture by He2+, Li3+, Be4+ and B5+ from atomic hydrogen in the ground state. The velocity range covered is from v=0.44 to v=2.8 au which corresponds to a laboratory energy range of from 5 to 200 keV amu-1. Reasonable agreement is obtained with the experimental data for He2+, Li3+ and B5+.
