Cross sections for the nonresonant charge transfer process D{sup +}+H (1s){yields}D(1s)+H {sup +} at low energies are calculated in hyperspherical coordinates. The method is free from all the inherent ambiguities associated with the conventional Born-Oppenheimer approach, such as the incorrect asymptotic energies and spurious couplings. However, like the Born-Oppenheimer approach, we show that hyperspherical potential curves and coupling terms have to be calculated only once to obtain results for all partial waves. Feshbach and shape resonances of HD{sup +} near the H(1s) threshold are also calculated. (c) 1999 The American Physical Society.
