SINGLE-CENTERED CALCULATIONS OF EXCITATION AND ELECTRON REMOVAL IN INTERMEDIATE-ENERGY PROTON HYDROGEN COLLISIONS

Single-centred expansion coupled states calculations are performed wit h basis sets large enough to achieve convergence. The particular colli sion system studied is p + H(1s) at energies of 15 keV and above. The results obtained establish the validity of this method for calculating excitation and electron removal cross sections even in situations whe re charge transfer is large. Cross sections for 1s --> 2l', 3l' and 4l ' excitation and for electron removal are presented and compared to ex periment and to other theoretical calculations.
