  In the linearized theory of gravity coupled to the electromagnetic field, we
calculate the cross sections of two processes in which both the gravitational
and electromagnetic interactions play a role. Those processes, in which a
graviton is produced in the final state, are: (a) the photoproduction of
gravitons off electrons and (b) the production of a photon and a graviton from
electron-positron annihilation. The motivation and outlook for these
calculations are discussed.
