Quantitative comparisons of results obtained from a semi-classical approximation and from the numerical solution of the time-independent Schriidinger equation are presented for interactions in a system of small reduced mass involving hydrogen as one of the collision partners. The differences in tran

A semiclassical collision modei has been irscd to cafcuhite the rate constant for vibrational reltxrtion in HD fu = 1, j = 0) colIid~ag with 4tie. The He + HD potential surface was obtained from an analyticat He + Hz surface previousfy used for similar c~caIatjons on NC f Hz and He + Dz\_ The fheorc
Quanta1 calculations of differential cross sections for vibrational excitation and vibronic charge transfer in the H+ -to? collision are reported. The calculations are undertaken within the infinite order sudden approximation using diabatic potential energy surfaces and the coupling terms of Grimber
Fully converged quantum cross sections for 4He-D2 (u= l,i=O) vibrational reliaxation were determined using the coupled-states method and a modikied version of the Gordon-Secrcst surface. First-order forbidden rotational transitions play a si@fkant role, comparable to that observed previously for the
