• 論文の詳細を見る

• The momentum spectra of the photoproduced positive and negative phonsfrom the reaction 7p+xnN have been measured using a tagged photon beamin the energy range from 710 MeV to 950 MeV. A magnetic spectrometer at 40'in the laboratory system is used to detect positive and negative pions. A hodoscopearray which surrounded the liquid hydrogen target was used to identify thedouble pion photoproduction process. From the measured momentum spectra,the cross sections of the reaction, 7'.p-+A-f-n were extracted. The results arewell reproduced by the coherent sum of GIOPE rnodel and ,v-channel resonancecontributions.
