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 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.

$\pi^+$ 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).
