Abstract: Describes the results from a preliminary analysis of an elastic electron-proton scattering experiment. We have measured cross sections for e-p scattering in the range of q{sup 2} from 0.7 to 25.0 (GeV/c){sup 2}, providing a large region of overlap with previous measurements. In this experiment we measure the cross section by observing electrons scattered from a beam passing through a liquid hydrogen target. The scattered particles are momentum analyzed by a magnetic spectrometer and identified as electrons in a total absorption shower counter. Data have been obtain with primary electron energies from 4.0 to 17.8 GeV and at scattering angles from 12.5 to 35.0 degrees. In general, only one measurement of a cross section has been made at each momentum transfer. In these circumstances, separation of the electric and magnetic form factors (G{sub E} and G{sub M}) cannot be made from our data. However, since the relation G{sub E} = G{sub M}/{mu} has been shown to hold at low momentum transfers and the contribution of G{sub E} to the cross section falls off rapidly with increasing q{sup 2}, we are able to indicate the behavior of the magnetic form factor at high momentum transfers.
