Abstract
In this dissertation, scattering of positronium (Ps) atoms by atomic hydrogen (H) and helium (He) targets has been reviewed at low and intermediate energies. This article mentions the measurements for He target and details the theoretical works employing eigenstate expansion method or the close-coupling approximation (CCA). Different versions of the CCA models have been discussed along with their merits and demerits. The other theoretical models employed for studying Ps impact scattering have also been touched. The dramatic difference in the measured data and the theoretical predictions for the zero energy results of He have been emphasized. Reasons for the difference amongst the theoretical predictions as well as the measured data at intermediate energies have been justified. Suggestions have been made for the future works to be carried out both theoretically as well as experimentally.
