An Investigation of the Influence of Scaling Laws on the Ratio of Neutron-Proton Charge Form Factor Calculations.
Abstract
An investigation of conventional and broken-symmetry scaling, and their effect on the ratio of the neutron-proton electric form factors, G sub En/G sub Ep, was carried out using measurements from elastic electron-deuteron and electron-proton scattering in the range of momentum transfers, q squared, of 0.10 <or=q squared <or= 0.80 F sup(-2), and electron scattering angles of 45 degrees to 120 degrees. Within experimental errors of available data in this range of momentum transfers and angles, it was concluded that both forms of scaling as applied to the deuteron form factor have negigible effect on the ratio G sub En/G sub Ep, and the application of either scaling law to the proton form factor results in nearly identical corrections to this ratio, thus allowing no distinction between them, and the agreement of the experimental data with the neutron-electron interaction slope at q squared approx = 0 is not influenced by the choice of scaling law. A conclusive test for the scaling laws would require an improvement in experimental accuracy by at least an order of magnitude, a technically nearly impossible requirement. (Author)
