Abstract

The differential cross section for the elastic scattering of deuterons by beryllium-9 has been measured for bombarding energies from 0.4 Mev to 1.8 Mev at the center-of-mass angles of 90°, 125°16', and 163°30'. The cross sections were found to be slowly-increasing functions of the bombarding energy and are compatible with the assumption that the scattering nuclei may be represented by nearly-impenetrable charged spheres. No resonance structure was observed. These results are in disagreement with earlier observations of Be^9 (d,d)Be^9 scattering from which the existence of two levels in B^(11), having excitation energies of 16.766 Mev and 16.912 Mev, respectively, was inferred. The results of this experiment indicate that the previously-observed elastic scattering anomalies were due to some shortcoming in the procedure of the earlier experiment.
