摘要：
Pseudoscalar mesons can be produced and studied in high-energy electron-nucleus scattering. We review and extend our previous theoretical analysis of meson production in the nuclear Coulomb field. The P -> gamma gamma decay rates are most directly determined for mesons produced in the double-Coulomb region where both photons are nearly real, and provided the hadronic-background contributions remain small. The larger the mass of the meson the higher the electron energy needed to assure such favorable conditions.
