The cross section for the reaction Li7(p, p) has been measured over the proton energy range 360-1400 kev. Measurements were made at scattering angles of 50, 70, 89.2, 110, 130, 143.4, and 160 degrees in the center-of-mass system. Anomalous scattering was observed near 441.5 kev, the resonance energy for the reaction Li7(p, γ), and near 1030 kev, the resonance energy for the reaction Li7(p, p′). Analysis of the results at 441.5 kev indicates a state in Be8 with J=1, even parity, formed by p wave protons. The relative stopping cross section for protons in lithium was also measured from 200-1300 kev.
