Charged-pi photoproduction at 180 degress in the energy range between 300 and 1200 mev

Fujii, T. ; Okuno, H. ; Orito, S. ; et al.
Phys.Rev.Lett. 26 (1971) 1672-1675, 1971.
Inspire Record 68981 DOI 10.17182/hepdata.21616

The differential cross sections at 180° for the reactions γ+p→π++n and γ+n→π−+p were measured using a magnetic spectrometer to detect π± mesons. In order to reduce the spread of energy resolution due to the nucleon motion inside the deuteron, a photon difference method was employed with a 50-MeV step for the reaction γ+n→π−+p. The data show structures at the second- and the third-resonance regions for both reactions. A simple phenomenological analysis was made for fitting the data, and the results are compared with those of previous analyses.

NEUTRAL PION PHOTOPRODUCTION ON THE DEUTERON

Imanishi, A. ; Ishii, T. ; Kato, S. ; et al.

Large-angle cross sections for γd→π0d are systematically measured in the photon energy range between 500 and 1000 MeV. A good fit is obtained by use of a Glauber-model calculation which includes the dibaryon resonances F33(2.26) and G41(2.51), but the fit has an unusual nature in the role of resonance and nonresonance contributions.

Neutral pion photoproduction from protons at forward angles in the energy region between 350 mev and 1175 mev

Hemmi, Y. ; Inagaki, Y. ; Inagaki, T. ; et al.
Phys.Lett.B 43 (1973) 79-84, 1973.
Inspire Record 84945 DOI 10.17182/hepdata.28128

The differential cross section for the reaction γp → π 0 p at forward angles has been measured in the energy region between 350 MeV and 1175 MeV. A phenomenological multiple analysis was carried out on the present data together with other data.

Photoproduction of neutral pions from neutrons between 500 and 900 mev

Hemmi, Y. ; Inagaki, T. ; Kikuchi, R. ; et al.
Phys.Lett.B 32 (1970) 137-140, 1970.
Inspire Record 63812 DOI 10.17182/hepdata.28720

The differential cross sections for the γ + n → π O + n reaction have been measured at the photon energies of 500–900 MeV. The ratios, R oo = [ d δ d Ω(γ n → π o n ) ] [ d δ d Ω(γ p → π o p ) ] , have been obtained at the c.m. pion angles of 60 O , 90 O , 105 O , 120 O , and 140 O .
