The nuclear scattering of gamma-rays from the Li⁷(p,γ)Be⁸ reaction has been measured. The scatterers used were Bi, Pb, Sn, and Cu. The observed Z dependence of the elastically scattered gamma-rays varied as Z^2.5±0.5, while the inelastically scattered gamma-rays varied at a rate greater than Z^2.9±0.3. An appreciable amount of inelastic scattering was observed.The elastic scattering results combined with previously measured integrated γ-n cross sections of Cu are in agreement with a gamma-ray absorption curve centered around 17-18 Mev and having a width of 4-6 Mev.
