Abstract
The elastic scattering and resonant charge transfer differential and integral cross sections in 
collisions are computed for the center-of-mass energy range of 
eV. Fully quantal and semiclassical approaches are utilized in these calculations. The reliability of the semiclassical approximation for very low collision energies is discussed. The results are compared with available data from the literature.
