The activation cross sections for the [sup 99]Tc(n,p)[sup 99]Mo, [sup 99]Tc(n,[alpha])[sup 96]Nb, [sup 99]Tc(n,n[prime][alpha])[sup 95]Nb, and [sup 99]Tc(n,n[prime])[sup 99n]Tc reactions at 13.5 and 14.8 MeV have been measured by using the deuterium-tritium neutron generator (the Fusion Neutronics Source) at the Japan Atomic Energy Research Institute. The results were compared with experimental values form the literature, evaluated activation cross-section files, and predictions by current cross-section computer codes. Special emphasis was placed on the feasibility of producing high-specific-activity [sup 99]Mo, to be used in medical applications, via the [sup 99]Tc(n,p)[sup 99]Mo reaction in the Fusion Material Irradiation Facility. A factor of 3 overestimate of [sup 99]Mo production resulted when the REAC[sup *]2 code was used. It is suggested that this discrepancy is due primarily to the factor of 5 difference in cross sections at the 14-MeV region between the REAC*2 data and the current measurement.
