Abstract

The best 3-channel projectile-inelastic [H(1s)+Ps(1s,2s,2p)] close-coupling approximation (CCA) is performed for positronium (Ps) and hydrogen (H) collision considering both the atoms in ground states at the incident channel. The s-wave elastic phase shifts and cross sections in the singlet and triplet channels and the total (or integrated) cross section are studied below inelastic threshold. Resonances in singlet channel using 2-channel and 3-channel projectile-inelastic CCAs confirm earlier prediction [1]. A resonance in triplet channel using 3-channel projectile-inelastic CCA is a new addition.
