Photoproduction of Charged Pions from Deuterium

Land, Robert H. ;
Phys.Rev. 113 (1959) 1141-1146, 1959.
Inspire Record 944993 DOI 10.17182/hepdata.26852

The photoproduction of charged pions from deuterium has been studied using a "monochromatic" gamma-ray beam of 292±8 Mev. The energy spectra of both positive and negative pions at the laboratory angle of 120° were determined and both agreed within experimental error with that predicted by the theory of Lax and Feshbach. The negative-to-positive ratio at 120° was 1.07±0.16, and within experimental error, was independent of meson energy. At an angle of 73° the ratio was 0.90±0.23 for 98.7 Mev mesons. The measured negative-to-positive ratio disagrees both with the simple classical picture of Brueckner and the phenomenological theory of Watson. Some results on the ratio using a bremsstrahlung beam are given.

Polarization of the Recoil Proton from pi0 Photoproduction in Hydrogen

Maloy, J.O. ; Peterson, V.Z. ; Salandin, G.A. ; et al.
Phys.Rev. 139 (1965) B733-B746, 1965.
Inspire Record 944960 DOI 10.17182/hepdata.26657

The polarization of the recoil proton in neutral single-pion photoproduction from hydrogen, γ+p→p+π0, has been measured for pion center-of-mass angles near 90° at 7 photon energies from 450 to 900 MeV. The polarization rises to a maximum of 0.58 near 600 MeV and is still 0.42 at 900 MeV. The sign of the polarization is negative in the sense of k×q, where k is the photon momentum and q is the pion momentum. The measured values are given as functions of laboratory photon energy and c.m. pion angle as follows: 450 MeV, 109°, -0.16±0.14; 525 MeV, 84°, -0.36±0.19; 585 MeV, 86°, -0.58±0.15; 660 MeV, 77°, -0.51±0.17; 755 MeV, 76°, -0.55±0.15; 810 MeV, 89°, -0.45±0.17; 895 MeV, 90°, -0.42±0.16. The recoil protons were momentum-analyzed with a magnetic spectrometer. Nuclear emulsion was used as scatterer and detector. The emulsion technique is discussed in detail. The number of individual scatterings in emulsion used for each measurement varied between 750 and 1000.

Large-Angle Pion-Proton Elastic Scattering at High Energies

Orear, J. ; Rubinstein, R. ; Scarl, D.B. ; et al.
Phys.Rev. 152 (1966) 1162-1170, 1966.
Inspire Record 50774 DOI 10.17182/hepdata.407

Differential cross sections for elastic π±−p scattering have been measured at lab momenta of 8 and 12 GeV/c in a momentum-transfer region corresponding to 1.2≤−t≤6 (GeV/c)2. Also, differential cross sections near 180° were measured for 4 and 8 GeV/c pions. At momentum transfers greater than −t=2 (GeV/c)2, the π−p cross sections drop much faster with increasing angle than the corresponding p−p cross sections. Also, in the region −t≃1.3 (GeV/c)2, there is structure in the π−p angular distribution but not in the p−p angular distribution. At −t≃3 (GeV/c)2, the drop in cross section appears to stop and from then on the angular distribution is consistent with isotropy. But in the angular region 170° to 180°, the cross sections have become much larger, and sharp backward peaks are observed. Information is given on the energy and charge dependences and widths of these backward peaks.
