The approximations used in a previous paper (I) by Tripathy and Rao for the evaluation of the matrix elements of the electron-proton and proton-proton interactions have been improved. The effect of the exponentially decaying potential-energy term on the capture cross section which had been ignored in I is also taken into consideration empirically by introducing a screening parameter. In this improved version, the departure of the capture cross section from experiment around 90 keV and above is removed, and the agreement with the experiment is found to be very good over a wide range of proton energies. Our study of the angular distributions shows dips in the differential scattering cross section similar to that of Jackson and Schiff for all energies. The behavior in angular distributions is somewhat different from that of a recent calculation by Glembocki and Halpern.
