摘要：

Differential cross sections of the 6Li(d,n'gamma)7Be, 6Li(d,p'gamma)7Li, 7Li(d,d'gamma)7Li and 19F(d,p'gamma)20F reactions were determined at three detection angles (0 degrees, 55 degrees and 90 degrees), for deuteron energies ranging from 1000 keV up to 2200 keV, with a 20 keV step. For the detection of the gamma-ray peaks of interest at E gamma = 429 keV, E gamma = 478 keV and E gamma = 656 keV, two different LiF targets were used. Three HPGe detectors having a 80% relative efficiency were placed around the targets for the detection of the gamma-ray peaks under study. The present results are compared with existing ones from the literature and the erroneous omission of the 7Li(d,d'gamma)7Li reaction contribution in the yield of the 478 gamma ray in natLi targets is discussed and analyzed. Comparisons with previously reported absolute thick target yields are also performed. Despite the fact that the differential cross sections determined in the present work are in very good agreement with previously reported differential cross-section datasets in literature (properly corrected), remarkable discrepancies in the case of existing absolute thick target yields are observed.
