The ratio of deep-inelastic e-n to e-p cross sections in the threshold region☆

We report measurements of the ratio of the deep-inelastic electron-neutron to electron-proton differential cross sections in the threshold (ω<3) region. The ratio was found to scale and to decrease monotically with decreasing ω. No violation of the quark model lower bound of 0.25 was observed in the ratio.

Tests of scaling of the proton electromagnetic structure functions

Abstract Deep-inelastic structure functions W 1 and W 2 have been extracted from electron-proton scattering cross sections that were measured in recent experiments at SLAC. The structure functions display deviations from scaling in the variable ω in the kinetic range 1.5 ⩽ ω ⩽ 3.0 and 2 ⩽ Q 2 ⩽ 15 GeV 2 .

Experimental Results on Scaling and the Neutron to Proton Cross Section Ratio in Deep Inelastic Electron Scattering

A review of present knowledge about the scaling of the neutron and proton structure functions and about the neutron to proton cross section ratio is presented. Emphasis is placed on the results of a recent electron scattering experiment at SLAC from which neutron cross sections were extracted from deuterium data using an impulse approximation.
