A description is given of the experimental techniques and investigation results of the parameters Σ , T , P for the γ p→p π 0 reaction using linear polarized photons and a polarized proton target. The measurements have been made in the photon energy range 280–450 MeV at pion c.m. angles between 60° and 135°. The new experimental data are used in an energy-independent channel multipole analysis without the Watson theorem.

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

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.
