A variable-energy gamma-ray system is described. Monoenergetic gamma radiation undergoing Compton scattering produced this energy variability over a significant range. The pararneters of the system are described. Gamma radiation from a Co/sup 60/ source of strength 1200 C was Compton scattered from a copper scatterer. The energy of the scattered radiation varies continuously from 1.33 Mev in the forward direction to 0.21 Mev at a scattering angle of 180 deg . The rays of mean energy 480 kev, corresponding to a mean scattering angle of 69.5 deg , were reasonantly scattered by lithium. From a self-absorption experiment the mean life of the first excited state of Li/sup 7/ was found to be (1.48 plus or minus 0.35) x 10/sup -13/ sec. (auth)
