Photoproduction of pi0 Mesons in Hydrogen

Koester, L.J. ; Mills, F.E. ;
Phys.Rev. 105 (1957) 1900-1913, 1957.
Inspire Record 945000 DOI 10.17182/hepdata.26900

This paper reports measurements of the total cross section from 150 to 240 Mev of incident photon energy and measurements of the 135° differential cross section from 180 to 215 Mev. A Monte Carlo evaluation of the γ-ray telescope efficiency by means of an electronic digital computer is outlined. The combined results indicate that a small but finite amount of S-state production occurs and that the angular distribution becomes flatter as the energy decreases. The latter effect is associated with production in unenhanced P-states and with a lack of electric quadrupole production. Good agreement with the Chew-Low theory is demonstrated by a comparison between the photoproduction and scattering of π0-mesons, where the scattering cross sections are derived from those for charged mesons by charge independence.

POSITIVE PION PRODUCTION BY POLARIZED BREMSSTRAHLUNG

Taylor, R.E. ; Mozley, R.F. ;
Phys.Rev. 117 (1960) 835, 1960.
Inspire Record 16518 DOI 10.17182/hepdata.26847

By selecting bremsstrahlung produced in a 0.003-in. aluminum radiator at a small angle from the original electron direction, a beam of polarized bremsstrahlung has been obtained from the Stanford linear accelerator. The variation of the polarization and intensity with angle has been studied and compared with theoretical predictions. The polarized beam has been used to study π+-meson production at 90° c.m. angle and photon energies of 242, 296, 337, and 376 Mev. The ratio of meson production along and at right angles to the electric field vector has been measured and compared with the values predicted by the relativistic dispersion relation.

High-Energy Proton Scattering from Carbon and Deuterium

Cocconi, G. ; Diddens, A.N. ; Lillethun, E. ; et al.
Phys.Rev. 126 (1962) 277-278, 1962.
Inspire Record 944981 DOI 10.17182/hepdata.26781

The momentum spectra of protons scattered from carbon and deuterium at angles close to 60 mrad and for incident proton momenta between 12 and 27 Gev/c have been measured. The data show good agreement with calculations based on plural quasi-elastic proton-nucleon scattering within the nucleus.

ELECTRON - PROTON SCATTERING AT LOW MOMENTUM ENERGIES

Lehmann, P. ; Taylor, R.E. ; Wilson, Richard ;
Phys.Rev. 126 (1962) 1183, 1962.
Inspire Record 16521 DOI 10.17182/hepdata.26811

We have measured the electron-proton scattering cross section at 248.9 Mev, 104.81°; 209.6 Mev, 149.75°; and 139.3 Mev, 104.19°. We find the following values: F1=0.767±0.025, F2=0.707±0.028, and F1F2=1.085±0.025 at −q2=2.98 f−2. F=0.902±0.011 at −q2=1.05 f−2. The last result agrees with previous measurements. The others are new contributions.

A COMPARISON OF ELECTRON - PROTON AND POSITRON - PROTON ELASTIC SCATTERING AT FOUR MOMENTUM TRANSFERS UP TO 5.0-GeV/c**2

Mar, J. ; Barish, Barry C. ; Pine, Jerome ; et al.
Phys.Rev.Lett. 21 (1968) 482-484, 1968.
Inspire Record 52726 DOI 10.17182/hepdata.21724

Measurements of the ratio (R) of positron-proton and electron-proton elastic-scattering cross sections have been made, with the square of the four-momentum transfer (q2) equal to 0.20, 0.69, 0.73, 1.54, 2.44, 3.27, 3.79, and 5.00 (GeV/c)2. The measurements, after radiative corrections, are consistent with R=1, with standard errors ranging from ±0.016 to ±0.123. The results give limits for the size of the two-photon effects.

High-Energy Inelastic e p Scattering at 6-Degrees and 10-Degrees

Bloom, Elliott D. ; Coward, D.H. ; DeStaebler, H.C. ; et al.
Phys.Rev.Lett. 23 (1969) 930-934, 1969.
Inspire Record 54874 DOI 10.17182/hepdata.21635

Cross sections for inelastic scattering of electrons from hydrogen were measured for incident energies from 7 to 17 GeV at scattering angles of 6° to 10° covering a range of squared four-momentum transfers up to 7.4 (GeV/c)2. For low center-of-mass energies of the final hadronic system the cross section shows prominent resonances at low momentum transfer and diminishes markedly at higher momentum transfer. For high excitations the cross section shows only a weak momentum-transfer dependence.
