When a photon undergoes Compton scattering, the energy E (Mev) of the scattered photon is determined by the incident energy E/sub o/ (Mev) and by the scattering angle theta . Therefore, a monochromatic gamma -ray source, in which the secondary gamma energy varies from E/sub 0//(1 + 2E/sub 0//0.511) to E/sub 0/ with theta , may be constracted. The intensities of the scattered-rays can be calculated by the Kiein-Nishina formula. There is a limit in the increase of the scattered rays by the use of a larger scatterer. The limit is attributed to the following: self-absorption of both the incident and the scattered rays by the large scatterer itself; multi-scattering in the scatterer; and energy shift by localization of the scattering. In addition, other kinds of radiation besides Compton-scattered rays should be considered, that is, coherent scattering radiation, fluorescent x-rays, and annihilation radiation. Experiments are made to obtain monochromatic rays in this way. (JAIF)
