MEASUREMENT OF THE RATIO OF THE PROTON FORM-FACTORS, G(E) / G(M), AT HIGH MOMENTUM TRANSFERS AND THE QUESTION OF SCALING

Litt, J. ; Buschhorn, G. ; Coward, D.H. ; et al.

Electron-proton elastic scattering cross sections have been measured at the Stanford Linear Accelerator Center at four-momentum transfers squared (q 2 ) of 1.0, 1.5, 2.0, 2.5and 3.75 (GeV/ c ) 2 . The angular distributions at q 2 = 2.5 and 3.75 (GeV/ c ) 2 are sufficient to provide values of the ratio G E / G M independent of the results from other laboratories. Our results are compatible with scaling, G E (q 2 ) = G M (q 2 )/ μ , within the experimental errors.

Elastic electron scattering from c-12 and o-16

Sick, I. ; Mccarthy, J.S. ;
Nucl.Phys.A 150 (1970) 631-654, 1970.
Inspire Record 62489 DOI 10.17182/hepdata.37092

Electron scattering cross sections for carbon and oxygen between q = 1 fm −1 and 4 fm −1 are given. The data are analysed in terms of a phenomenological charge distribution and new information concerning the tail and the center of the charge distribution are obtained. The presence of dispersion effects appears to be necessary to explain the cross sections in the first diffraction minimum. The effect of a finite potential and short range correlations on the form factor are discussed.

K- p charge exchange at 3.95 gev/c

Moscoso, L. ; Hubbard, J.R. ; Leveque, A. ; et al.
Phys.Lett.B 32 (1970) 513-514, 1970.
Inspire Record 63099 DOI 10.17182/hepdata.28711

The charge excharge reaction K − p → K 0 n has been studied in a event/μb exposure of the CERN 2m hydrogen bubble chamber to a 3.95 GeV/ c K − beam. The differential cross section d σ /d t exhibits a change of slope at −1 ≈ 0.8 GeV 2 .

COMPTON SCATTERING FROM HYDROGEN BETWEEN 5-GeV AND 17-GeV

Anderson, Robert L. ; Gustavson, D. ; Johnson, J.R. ; et al.
Phys.Rev.Lett. 25 (1970) 1218, 1970.
Inspire Record 60845 DOI 10.17182/hepdata.21597

Measurements have been made on Compton scattering for photon energies between 5 and 17 GeV and t values from -0.06 to -1.1 (GeVc)2. The data were obtained by performing a coincidence between the Stanford Linear Accelerator Center 1.6-GeVc spectrometer and a Lucite shower counter. The scattering appears diffractive out to high t values, but the cross sections seem not to be in good agreement with the prediction of a strict vector-meson-dominance model.

Charged-pi photoproduction at 180 degress in the energy range between 300 and 1200 mev

Fujii, T. ; Okuno, H. ; Orito, S. ; et al.
Phys.Rev.Lett. 26 (1971) 1672-1675, 1971.
Inspire Record 68981 DOI 10.17182/hepdata.21616

The differential cross sections at 180° for the reactions γ+p→π++n and γ+n→π−+p were measured using a magnetic spectrometer to detect π± mesons. In order to reduce the spread of energy resolution due to the nucleon motion inside the deuteron, a photon difference method was employed with a 50-MeV step for the reaction γ+n→π−+p. The data show structures at the second- and the third-resonance regions for both reactions. A simple phenomenological analysis was made for fitting the data, and the results are compared with those of previous analyses.

Resonance production in k- neutron interactions at k- momenta of 1.45 and 1.65 gev/c

Colley, D.C. ; Cox, G.F. ; Eastwood, D. ; et al.
Nucl.Phys.B 31 (1971) 61-85, 1971.
Inspire Record 68588 DOI 10.17182/hepdata.33257

Results are reported on K − -neutron interactions at c.m. energies near 2 GeV. The interactions are dominated by strong production of hyperon resonances, particularly Σ(1385), Λ(1405) and Λ(1520). Production cross sections and angular distributions are given for the Σ(1385), Λ(1405) and Λ(1520) and branching fractions to decay modes observed in the experiment are given for Σ(1385) and Λ(1520). The strong energy dependence of some features of the data suggests that s -channel effects are dominant.
