We report the results from measurements of proton polarization P , in the γ +D→p+n reaction at photon energies ranging from 200 to 350 MeV. The data obtained are compared with the measured analysing power A , of the reverse reaction and with model calculations. The assumption of the dominant contribution of isobar configurations in this region is on the whole confirmed by the present proton polarization measurements.

Coincidence electroproduction of single neutral pions in the resonance region at q 2 = 0.5 (GeV/ c ) 2

Latham, A. ; Allison, J. ; Booth, I. ; et al.

Nucl.Phys.B 156 (1979) 58-92, 1979.

Inspire Record 1392686 DOI 10.17182/hepdata.836

Data are presented for the reaction ep → ep π 0 at a nominal four-momentum transfer squared of 0.5 (GeV/ c ) 2 . The data were obtained using an extracted electron beam from NINA and two magnetic spectrometers for coincidence detection of the electron and proton. Details are given of the experimental method and the results are given for isobar masses in the range 1.19 – 1.73 GeV/ c 2 .

Measurement of the angular dependence of the polarization of the recoil protons from the photoproduction of neutral pions on hydrogen at proton energies between 240 and 420 MeV

Althoff, K.H. ; Finken, D. ; Minatti, N. ; et al.

Phys.Lett.B 26 (1968) 677-678, 1968.

Inspire Record 1392747 DOI 10.17182/hepdata.29304

New measurements of the polarization of the recoil protons from the reaction γ + p → π o + p are reported for the region of the first resonance. These measurements are an extension of earlier experiments, done on the 500 MeV-electron-synchroton. More data have been taken at photon energies of 240, 300, 360 and 420 MeV.

Phys.Lett.B 26 (1967) 41-44, 1967.

Inspire Record 1392746 DOI 10.17182/hepdata.29332

Measurements of the photoproduction from hydrogen of single K + mesons at gamma ray energies of 3.4 and 5.0 GeV and at laboratory angles of 5.1°, 7.1°, 9.9° and 15.1° are reported. The s dependence at fixed t is derived for momentum transfers of −0.25 and −0.37 (GeV) 2 .

Pion production with polarized photons and test of vector dominance model

Geweniger, Chr. ; Heide, P. ; Kötz, U. ; et al.

Phys.Lett.B 28 (1968) 155-156, 1968.

Inspire Record 1392676 DOI 10.17182/hepdata.29098

Cross section asymmetries for the sum of single π + and π - production with polarized photons of 3.4 GeV have been measured. The results disagree with calculations based on the vector dominance model using experimental data of vector meson production in π beams.
