The Ratio of Deep - Inelastic e-n to e-p Cross-Sections in the Threshold Region

Bodek, A. ; Dubin, D.L. ; Elias, J.E. ; et al.
Phys.Lett.B 51 (1974) 417-420, 1974.
Inspire Record 91646 DOI 10.17182/hepdata.27946

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.

Comparisons of Deep Inelastic e p and e n Cross-Sections

Bodek, A. ; Breidenbach, M. ; Dubin, D.L. ; et al.

Cross sections for inelastic scattering of electrons from hydrogen and deuterium were measured for incident energies from 4.5 to 18 GeV, at scattering angles of 18°, 26°, and 34°, and covering a range of squared four-momentum transfers up to 20 (GeVc)2. Neutron cross sections were extracted from the deuterium data using an impulse approximation. Comparisons with the proton measurements show significant differences between the neutron and proton cross sections.

Inelastic electron-Proton Scattering at Large Momentum Transfers

Miller, Guthrie ; Bloom, Elliott D. ; Buschhorn, G. ; et al.
Phys.Rev.D 5 (1972) 528, 1972.
Inspire Record 67123 DOI 10.17182/hepdata.22355

Differential cross sections for electrons scattered inelastically from hydrogen have been measured at 18°, 26°, and 34°. The range of incident energy was 4.5 to 18 GeV, and the range of four-momentum transfer squared was 1.5 to 21 (GeVc)2. With the use of these data in conjunction with previously measured data at 6° and 10°, the contributions from the longitudinal and transverse components of the exchanged photon have been separately determined. The values of the ratio of the photoabsorption cross sections σSσT are found to lie in the range 0 to 0.5. The question of scaling of 2MpW1 and νW2 as a function of ω is discussed, and scaling is verified for a large kinematic range. Also, a new scaling variable which reduces to ω in the Bjorken limit is introduced which extends the scaling region. The behavior of σT and σS is also discussed as a function of ν and q2. Various weighted sum rules of νW2 are evaluated.
