The elastic scattering of deuterons by lithium-7 nuclei has been investigated in the energy region from 0.400 to 1.800 Mev. Three excitation functions, and twenty angular distributions have been measured in the energy range studied. The scattering cross sections tend to be lower than the Rutherford value below about 0.850 Mev and then rise to values several times the Rutherford value for higher energies. A prominent anomaly occurs in the scattering cross section near one Mev where the reaction cross sections also show resonance, while there is no obvious anomaly corresponding to the reaction resonances near 0.800 Mev. The entire energy region investigated shows evidence of many broad overlapping energy levels in the compound nucleus. It was therefore not possible to make a detailed analysis of the elastic scattering over the entire region, from which level parameters might have been obtained. An s-wave analysis provides an adequate fitting of the angular distributions up to about one Mev, and the relatively sharp anomaly near one Mev appears to be due to p-wave deuterons.
