An investigation of conventional and broken -symmetry scaling,
and their effect on the ratio of the neutron-proton electric form
factors, G^ /G„ , was carried out using measurements from elastic
En Ep
electr on-deuter on and electron-proton scattering in the range of
2 2 -2
momentum transfers, q , of O.lO^q ^0.80 F , and electron scattering
angles of 45 to 120 . 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„ /G^ , and the
En Ep
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
2
data with the neutron-electron interaction slope at q — is not
influenced by the choice of scaling lav/. 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.
