Investigation of the 27Al(d,x)24Na nuclear reaction for deuteron beam monitoring purpose

Abstract

Activation cross-sections for the 27Al(d,x)24Na nuclear reaction was measured by using a stacked-foil activation technique combined with high purity germanium (HPGe) γ-ray spectrometry over deuteron energy range of 2–24 MeV. Measured data were critically compared with the available literature data and also with the theoretical data extracted from the TENDL data base. Accuracy of the 27Al(d,x)24Na cross-sections were confirmed by the simultaneous measurements of the natTi(d,x)48V monitor reaction cross-sections. Present results reproduced well the IAEA recommended natTi(d,x)48V reaction cross-sections, but provide slight deviation with the IAEA recommended 27Al(d,x)24Na cross-sections. It may be concluded that the use of 27Al(d,x)24Na in deuteron beam monitoring should not be a perfect choice if one has the option to use the natTi(d,x)48V reaction.
