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 .

ELECTROPRODUCTION OF SINGLE CHARGED PIONS FROM DEUTERIUM AT Q**2 APPROXIMATELY 1-GEV**2 IN THE RESONANCE REGION

Vapenikova, O. ; Allison, John ; Dickinson, B. ; et al.
Z.Phys.C 37 (1988) 251-258, 1988.
Inspire Record 263398 DOI 10.17182/hepdata.898

We present differential cross-sections for the electro-production of single charged pions from deuterium for a virtual photon mass squared −1.0 GeV2 and for pion nucleon masses in the range 1.23–1.68 GeV (the 1st and 2nd resonance regions). The data are compared with predictions from fits to hydrogen data.

Data are presented for the reaction ep → ep π 0 at a nominal momentum transfer squared of 1.0 (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. Differential cross sections have been measured for isobar masses in the range 1.19–1.73 GeV/ c 2 .

Photoproduction of neutral pions on hydrogen at photon energies between 200 and 440 mev

Fischer, G. ; Fischer, H. ; Von Holtey, G. ; et al.
Nucl.Phys.B 16 (1970) 93-101, 1970.
Inspire Record 62733 DOI 10.17182/hepdata.16659

Differential cross sections for neutral-pion photoproduction on hydrogen in the region of the first resonance have been measured by two independent experiments detecting the recoil protons. The results of both measurements have been combined into one set of cross sections covering the photon energy range from 200 to 440 MeV at pion c.m. angles between 50 and 160 degrees.
