Abstract
Positronium formation in positron-hydrogen collisions is studied using Schw inger's variational principle at intermediate energies. A total of 12 corre lated functions in the basis set expansion is found to be sufficient to pre dict accurate cross sections in agreement with the experimental and theoret ical values available in the literature.
