  Pseudoscalar mesons can be produced and studied in high-energy
electron-nucleus scattering. We review and extend our previous analysis of
meson production in the nuclear Coulomb field. The $P\rightarrow \gamma \gamma$
decay rates are most directly determined for mesons produced in the
double-Coulomb region where both photons are nearly real, and provided the
background-hadronic contribution remains small. The larger the mass of the
meson the higher the electron energy needed to assure such a condition.
