Measurements of the Polarization Parameters in G and $H$ in Positive Pion Photoproduction

Bussey, P.J. ; Rutherglen, J.G. ; Booth, P.S.L. ; et al.
Nucl.Phys.B 169 (1980) 403-414, 1980.
Inspire Record 152385 DOI 10.17182/hepdata.43803

Measurements have been made of the polarisation parameters G and H for the process γ p→ π + n in the photon energy range 600–1875 MeV and pion c.m. angles between 30° and 100°. These data were obtained in a double polarisation experiment, in which the polarised photon beam from the Daresbury electron synchrotron was incident upon a polarised proton target. Theoretical predictions from a current analysis are compared with the data.

POLARIZATION OF RECOIL PROTONS FROM THE REACTION GAMMA P ---> PI0 P IN THE PHOTON ENERGY RANGE 450-MEV - 800-MEV

Bratashevsky, A.S. ; Gorbenko, V.G. ; Derebchinsky, A.I. ; et al.
Nucl.Phys.B 166 (1980) 525-533, 1980.
Inspire Record 157933 DOI 10.17182/hepdata.34552

Measurement of secondary-proton polarization from the reaction γ p → π 0 p have been performed in the proton energy range 500–800 MeV at c.m. pion emission angles 100°, 120°, 140°. The experiment was carried out using an optical spark chamber telescope at the output of the magnetic spectrometer. The obtained experimental data are included in a Walker-type analysis in order to verify the parameters of the resonances P 11 (1470), D 13 (1570) and S 11 (1535). Proton polarization in the reaction γ p → π 0 p was measured for a photon energy of 450 MeV at a c.m. pion emission angle of 105° using photons linearly polarized at 45° to the reaction plane. A liquid hydrogen target in the field of a superconducting magnet was used for the separation of the P x ′ and P z ′ components of the secondary-proton polarization vector.

Measurements of the Double Polarization Parameters $G$ and $H$ in Neutral Pion Photoproduction

Bussey, P.J. ; Rutherglen, J.G. ; Booth, P.S.L. ; et al.
Nucl.Phys.B 159 (1979) 383-396, 1979.
Inspire Record 141663 DOI 10.17182/hepdata.34624

Measurements have been made of the double polarisation parameters G and H in the photoproduction of neutral pions from protons, for incident photon energies between 1300 MeV and 2300 MeV and for pion c.m. angles between 50δ and 80δ. The results are compared with predictions from a recent comprehensive analysis of earlier photoproduction data.

Polarization Parameters in Positive Pion Photoproduction

Bussey, P.J. ; Raine, C. ; Rutherglen, J.G. ; et al.
Nucl.Phys.B 154 (1979) 205-225, 1979.
Inspire Record 140382 DOI 10.17182/hepdata.43832

Measurements have been made of the polarisation parameters Σ , T and P for the process γ p → π + n in the photon energy range 520–2250 MeV at c.m. angles between 30° and 120°. These data were obtained in a double polarisation experiment, using the polarised photon beam from the Daresbury electron synchrotron incident on a polarised proton target. The data are compared with predictions from current theoretical analyses.
