The differential cross section for the elastic scattering of deuterons by beryllium has been measured for bombarding energies from 0.4 to 1.8 MeV at the center-of-mass angles of 90°, 126°16′, and 163°30′. The ratios of the observed differential cross sections to the Rutherford cross sections were found to be slowly increasing functions of the bombarding energy. Over the energy range of the present experiment these ratios are compatible with the simple assumption that the scattering nuclei can be represented by nearly impenetrable charged spheres. Since no resonance structure was observed in this work, these results disagree with previously published work on the elastic scattering of deuterons by beryllium in which prominent scattering anomalies were reported at $E_d=1.16\mathrm{}$ and 1.35 MeV.
