The elastic scattering of deuterons by beryllium


Renken, James H. (1963) The elastic scattering of deuterons by beryllium. Dissertation (Ph.D.), California Institute of Technology.


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.
