Description
Ground-state capture cross sections in e+-H2 scattering are calculated in the energy region 10-1000 eV using the first Born approximation. The approximation employed by Sural and Mukherjee in predicting the first Born capture cross section is found to be unjustified. Present capture cross sections for incident positron energies E ≥ 30eV are in good agreement with the measured data. (Author)
