Abstract
The cross sections for the reactions and have been determined and the excitation functions obtained for deuteron bombarding energies of 0.30 to 3.00 Mev. At a bombarding energy of 1.16 Mev, the cross section is 44 mb, and the cross section is 280 mb. Resonances in the excitation function occur at values which correspond to excited levels in at 13.69, 13.91, 14.27, and 14.94 Mev. The rapidly rising smooth excitation curve for the reaction indicates a barrier penetration with some evidence for weak resonances corresponding to excited states in at 15.18 Mev and 15.69 Mev.
Attempts were made to detect the reaction ; it was possible to set only an upper limit of 0.1 mb on the cross section for this reaction at a bombarding energy of 1.16 Mev.
Scintillation spectrometry of the decay shows the ratio of the intensities of the 6.133 and 7.10 Mev -rays to be 1:0.81.
