Abstract
Our recently developed two-centre atomic orbital (TCAO) close-coupling method is applied to - H(1s) collisions in the impact energy range from . Convergent cross sections are obtained for this system by using a large number of bound and pseudostate basis functions on the target and a limited number of bound states on the projectile. Cross sections for electron transfer to 1s, , , and , for excitation to , , and and for ionization are presented and compared with available experimental data and other theoretical calculations. The accuracy of the previous TCAO close-coupling calculations is challenged and the reliability of some experimental data for this system is questioned.
