Abstract
The n=2 excited state capture cross sections in e+-H2 scattering have been calculated using the first Born approximation. The integrated and differential capture cross sections are predicted in the energy range 30-1000 eV. The total Ps formation cross sections ( sigma TPs= sigma rgPs+ Sigma 2sPs+ sigma 2pPs) are found to be in good agreement with the measured values in the energy range 50-150 eV.
