Abstract
The differential cross-section for the 15.1MeV gamma ray produced by the 11B(d,nγ)12C reaction in a thick natural boron target has been measured for incident deuteron energies ranging from reaction threshold to 5MeV. Measurements for a thin natural boron target have been carried out over a similar incident deuteron energy range. These results are compared to previous measurements made by Kavanagh (1958) and Kuan (1964). Measurements of the combined thick target yield for the 6.129, 6.917, and 7.116MeV gamma rays from the 19F(p,αγ)16O reaction have been carried out on a stopping thickness sulfur hexafluoride gas cell for effective incident proton energies ranging from 1 to 4MeV as a consistency check on the procedure used for normalization of the detector response function. The results for the 11B(d,nγ15.1)12C yield a significantly lower cross-section than that previously reported, while the measurements of the 19F(p,αγ) reaction are consistent with previous measurements made by Fessler (2000) and Micklich (2003).
