Singly differential cross sections with exchange for Ps-fragmentation
Hasi Ray
Ps ionization in Ps-atom scattering is of fundamental importance. The singly differential cross sections (SDCS) provides more accurate information to test a theory than integrated…

Target-ionization with exchange in Ps-atom scattering
Hasi Ray
A proposal is made by the University College of London Group [1] for measuring the target-ionization cross sections in Ps and atom scattering. We calculate the corresponding theore…

Resonances in Ps-H scattering
Hasi Ray
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 at…
