Abstract
During the routine production of the beta(+)-emitting radioisotope O-1 5 via the N-14(d,n)O-15 reaction small quantities of N-13 and C-11 are also formed. The excitation functions of the nuclear processes N-14(d ,t+dn)N-13 and N-14(d,alpha n)C-11 were determined experimentally from their respective thresholds up to 12.3 MeV. Substantial new informati on was obtained as compared to the literature data. From our cross sec tion values the ratios of impurities to O-15 were calculated. Those ra tios were compared with the results of integral measurements done on t arget gas samples irradiated under production conditions. The optimum on-target deuteron energy is less than or equal to 10 MeV.
