Resonance nucleon scattering amplitude in the photonuclear reaction
Abstract
The cross section of the photonuclear reaction in the nucleon-resonance region is calculated to search the resonance-nucleon scattering amplitude in the nucleus. It is assumed that the resonance R is produced and decayed in the elementary photon-nucleon (γ N) reaction in the nucleus as γ N R γ N. The resonance interacts with the nucleons while propagating through the nucleus. Therefore, the calculated photonuclear reaction cross section is compared with the data to extract the resonance-nucleon scattering parameters in the nucleus.
