Abstract

During the routine production of the β+-emitting radioisotope 15O via the 14N(d,n)15O reaction small quantities of 13N and 11C are also formed. The excitation functions of the nuclear processes 14N(d,t + dn)13N and 14N(d,αn)11C were determined experimentally from their respective thresholds up to 12.3 MeV. Substantial new information was obtained as compared to the literature data. From our cross section values the ratios of impurities to 15O were calculated. Those ratios were compared with the results of integral measurements done on target gas samples irradiated under production conditions. The optimum on-target deuteron energy is ≤ 10 MeV.
