Abstract
The differential cross sections of the γ+ d →π 0 + d reaction have been measured at the pion angle of 50° in the center of mass system and in the photon energy range from 650 MeV to 820 MeV, for the purpose of estimating the isotopic vector part of the photopion production amplitude from nucleons around the second resonance, N 1/2 * (1525). Recoiled deuterons were measured with the combination of the momentum analysis with a magnet and the time of flight measurement. The measured cross section together with data obtained by us in the previous experiment were analysed basing on the impulse approximation. The s 11 -, s 31 -, p 33 -, p 11 - and d 13 -waves are included in the analysis. The results of analysis are consistent with the conclusion that the isotopic vector part is dominant in the d 13 -wave amplitude of π 0 photoproduction from free nucleons around the N 1/2 * (1525) resonance.Keywords
