SINGLE-CENTERED CALCULATIONS OF EXCITATION AND ELECTRON REMOVAL IN INTERMEDIATE-ENERGY P+H(N=2) COLLISIONS

Large-basis single-centred expansion calculations have been previously shown to yield accurate cross sections for collisions between protons and ground state hydrogen atoms. In the present paper the method is e xtended to p + H(n = 2) collisions. Cross sections for 2s and 2p --> 3 l' and 4l' excitation and for electron removal from 2s and 2p are pres ented and compared to other theoretical calculations.
