NN coupling and two-pion photoproduction on the nucleon
M. Hirata, N. Katagiri, T. Takaki
Effects of non-resonant photoproductions arising from two different couplings are investigated in the reaction. We find that the pseudoscalar (PS) coupling i…
Nuclear Photoabsorption at Photon Energies between 300 and 850 Mev
M. Hirata, N. Katagiri, K. Ochi +1
We construct the formula for the photonuclear total absorption cross section using the projection method and the unitarity relation. Our treatment is very effective when interferen…
Effect of channel in the reactions
M. Hirata, K. Ochi, T. Takaki
A model for the two-pion photoproduction on the nucleon proposedearlier is modified to simultaneously explain the total cross sections and the invariant mass spectra. Using this mo…
Cooperative damping mechanism of the resonance in the nuclear photoabsorption
M. Hirata, K. Ochi, T. Takaki
We propose a resonance damping mechanism to explain the disappearance of the peaks around the position of the resonances higher than the resonance in the nuclear photoabsorptio…
Photoabsorption on a Nucleon in the D_{13} Resonance Energy Region
Kazuyuki Ochi, Michihiro Hirata, Takashi Takaki
We present a simple model for the reaction which reproduces the cross sections of the and channels over the range of the…
