โœฆ Synopsis

This paper presents accurate computation of the differential cross sections for the elastic and vibrational excitation of ground state Hz by fast electrons. The electronic matrix elements are evaluated at 20 internuclear separations and proper averaging over vibrational wavefunctions is carried out. The comparison to experiment yields ex-&lent agreement. Different computational procedures sppropriate for low and moderate values of momentum transfer are compared.

Within a framework of the Born approximation simplified by czrtain assumptions, a procedure is given which esplicitly constructs a nonlocal potential that provides a fit to elastic: scattering data. The data arc assumed to consist of the scntterinf amplitude as a functicn of the momentum transfer ov
