Differential Cross Sections in Eta Photoproduction from 0.8 to 1.45 GeV

Bloom, E.D. ; Heusch, C.A. ; Prescott, C.Y. ; et al.
Phys.Rev.Lett. 21 (1968) 1100-1103, 1968.
Inspire Record 54471 DOI 10.17182/hepdata.21721

The cross section for the process γp→pη was studied from 0.8- to 1.45-GeV incident photon energy at center-of-mass angles from 50 to 90°. The data cover a range of energies well beyond previous measurements. The results will aid in the study of I=12 nucleon isobars.

Photoproduction of pi0 Mesons from Hydrogen at 180-degrees

Cassiday, G.L. ; Fischer, H. ; Ito, A. ; et al.
Phys.Rev.Lett. 21 (1968) 933-934, 1968.
Inspire Record 944912 DOI 10.17182/hepdata.21702

We measured the π0 photoproduction differential cross section at 180° for a range of incident photon energies between 650 and 1750 MeV. The cross sections are dominated by the D13(1525), D15(1688), and F37(1920) resonances.

Pi-+ photoproduction in forward direction

Ito, A. ; Loe, R. ; Loh, E.C. ; et al.
Phys.Rev.Lett. 24 (1970) 687-690, 1970.
Inspire Record 62934 DOI 10.17182/hepdata.21670

The ratio of π− to π+ off deuterium was measured as a function of incident photon energy from 600 to 1700 MeV in the forward direction. The ratio shows a broad dip around a center-of-mass energy of 1700 MeV, resulting presumably from the collective effect of several isospin-½ resonances in this energy region. Such a change in the ratio is reflected in the rapid variation of the isoscalar photoproduction amplitude since we found the isovector photoproduction amplitude to be a relatively smooth function decreasing slowly with increasing incident photon energy.

pi+ Photoproduction from Hydrogen at Lab Angles from 34-degrees to 155-degrees and Lab Photon Energies from 500 to 1350 MeV

Thiessen, Henry A. ;
Phys.Rev. 155 (1967) 1488-1496, 1967.
Inspire Record 52277 DOI 10.17182/hepdata.26588

The differential cross section for the reaction γ+p→π++n was measured using the Caltech 1.5-GeV electron synchrotron. The positive pions were detected and momentum analyzed in a multichannel magnetic spectrometer and the data were recorded in the memory of a pulse-height analyzer. The energy resolution was improved over previous experiments and an attempt was made to minimize systematic errors. The data are presented in the form of energy distributions at 12 lab angles from 34° to 155°, and the range of lab proton energies extended from 500 to 1350 MeV. Data were not taken at all energies for each angle, since the maximum useful momentum of the spectrometer, 600 MeVc, restricted the maximum energy for lab angles less than or equal to 74°.

Electron-Proton Scattering at High-Momentum Transfer

Berkelman, K. ; Feldman, M. ; Littauer, R.M. ; et al.
Phys.Rev. 130 (1963) 2061-2068, 1963.
Inspire Record 46839 DOI 10.17182/hepdata.26788

The elastic electron-proton scattering cross section has been measured at laboratory angles between 90° and 144° and for values of the four-momentum transfer squared between 25 and 45 F−2 (incident electron laboratory energies from 830 to 1360 MeV). Both the scattered electrons and the recoil protons were momentum analyzed and counted in coincidence, making possible background-free measurements down to cross sections of the order of 10−35 cm2/sr. The data are consistent with the Rosenbluth formula, and the resulting form factors tie on well with previous measurements at lower momentum transfer, continuing the established trend.

$\pi^{-}+ p$ elastic scattering at 1 200 MeV

Bertanza, L. ; Carrara, R. ; Drago, A. ; et al.
Nuovo Cim. 19 (1961) 467-481, 1961.
Inspire Record 1184999 DOI 10.17182/hepdata.1109

A bubble chamber investigation of π−+p elastic scattering at 1 200 MeV (K.E.) is reported. The total and differential cross-sections are determined. By extrapolation of the angular distribution, the 0° cross-section is derived and compared with the results obtained with the help of the dispersion relations and the optical theorem. The forward peak is investigated in terms of diffraction scattering and a value for the optical radius is derived.
