Gamma rays from beryllium bombarded with alpha particles and from boron bombarded with deuterons

[摘要] Because the evidence on the polonium-beryllium gamma ray spectrum is of a somewhat doubtful nature, mainly due to statistical difficulties, it was believed desirable to make a careful investigation of this spectrum with a pair spectrometer. This was made possible by the loan of a two curie polonium-beryllium source from Los Alamos Scientific Laboratory.It was believed desirable also to investigate the gamma spectrum from boron isotopes bombarded with deuterons, since this had never been done with separated isotopes and the assignment of the gamma ray lines to the two isotopes was uncertain. This spectrum gives information on some of the same levels in C12 involved in the Be9(alpha,n)C 12 reaction. The separated B10 isotope was obtained from Oak Ridge National Laboratory.
