Photoproduction of pseudoscalar mesons on 1p-shell nuclei at high energies and forward angles

I address the issue of coherent and incoherent photoproduction of pseudoscalar mesons on nuclei at high photon energies in the peripheral region, characterized by small momentum transfer. The reactions considered give prominent background to photoproduction in the electromagnetic field of a nucleus. For this reason, a detailed knowledge of their cross sections is necessary for correct determination of the radiative decay widths of neutral mesons. Particular attention is paid to transitions to the discrete bound levels, as well as to the giant resonance states. Numerical results are presented for photoproduction of II mesons on 12C.

This paper addresses the coherent and incoherent photoproduction of pseudoscalar mesons on nuclei at high photon energies, particularly in the peripheral region with small momentum transfer. The reactions considered are important background for photoproduction in the electromagnetic field of a nucleus, and accurate cross section measurements are necessary for determining the radiative decay widths of neutral mesons. The study focuses on transitions to discrete bound levels and giant resonance states, with numerical results presented for photoproduction of II mesons on 12C.
