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.13 pages; uses axodraw for 3 figuresHigh Energy Physics - PhenomenologyPhotogravitational processestext
