摘要：
The coherent eta-meson energy E eta distribution spectra in proton nucleus reactions have been calculated to investigate the pi(0)-eta mesons' interference, in addition to the study of resonance N* dynamics in the nucleus. The elementary reaction occurring in the nucleus is assumed to proceed as pN -> pN* ; N* -> N eta. Born terms in the intermediate state are also considered. In a scalar-isovector nucleus, this reaction occurs because of pi(0)- and eta- meson exchange interactions for the forward going proton and the eta meson; other meson exchange potentials do not contribute to this process. The sensitivity of the cross section to the hadron nucleus interactions and the beam energy dependence of the cross section are studied for this reaction.
