$\pi^+$ Photoproduction Between 1.2 and 3 GeV at Very Small Angles

Buschhorn, G. ; Carroll, J. ; Eandi, R.D. ; et al.
Phys.Rev.Lett. 18 (1967) 571-574, 1967.
Inspire Record 52312 DOI 10.17182/hepdata.21767

The reaction γ+p→π++n has been investigated for photon energies between 1.2 and 3 GeV and pion c.m. angles from 2.5 to 15°. The cross section is strongly peaked in the forward direction and shows resonance structure in the region of the N32*(1920) and N12*(2190).

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.

K+Lambda Photoproduction from Hydrogen at 1200 MeV

Peck, Charles W. ;
Phys.Rev. 135 (1964) B830-B838, 1964.
Inspire Record 46599 DOI 10.17182/hepdata.26722

Measurements of the angular distribution of the cross section for the photoproduction of the K+Λ system from hydrogen have been made in the c.m. angular interval from 15° to 85° at a photon energy of 1200 MeV. The reaction was identified by detecting the K+ mesons with a magnet spectrometer and a velocity selection system consisting of two Čerenkov counters. The angular distribution at this energy is very similar to that at lower energies in that it is peaked forward and is easily fit with a quadratic in cosθc.m.. Special emphasis was placed on the forward direction in an attempt to find evidence for the one-K-exchange pole. A Taylor-Moravcsik analysis of the data is presented, but the results are inconclusive.

Backward Photoproduction of pi0 in the Region of the P-33 Pion-Nucleon Resonance

Croissiaux, M. ; Dally, E.B. ; Morand, R. ; et al.
Phys.Rev. 164 (1967) 1623-1634, 1967.
Inspire Record 52290 DOI 10.17182/hepdata.26529

The π0 photoproduction cross section has been measured at 180° for photon energies from 220 to 380 MeV, in steps of 20 MeV, by detecting the recoil proton at 0°. The statistical accuracy of the measurements varies between 3 and 7%, depending on the energy. Absolute cross sections have been deduced from a comparison of the measurements with electron-proton scattering. The experimental data are compared with theoretical results calculated from fixed-momentum-transfer dispersion relations. Special attention is paid to the prediction of the multipoles at the first resonance, namely, E1+32, M1+32, and E0+π0 to obtain agreement with experiment.
