99Tc in stars, reactors, and nuclear medicine

Abstract The roles of 99g Tc in stars and nuclear fission reactors that 99m medicine were studied using neutrons provided from accelerators are reported. In addition to the critical role stars, we also describe related light nuclei such as 16 O, experimental studies on keV-neutron capture cross sections these performed keV a 3.2-MV Pelletron accelerator section Tc, is important nucleosynthesis 99 transmutation long-lived wastes produced reactors, measured. both measured neutron time-of-flight method with ns-pulsed source 7 Li( p , n ) Be reaction an anti-Compton γ - ray NaI(Tl) spectrometer. measurements reported here compared values recent worldwide evaluated data libraries. We proposed producing 100 Mo( ,2 Mo reaction, production experiment nat sample MeV C( d by 40 deuterons at cyclotron. Calculations for enriched performed, calculated results results. Moreover, thermoseparation was discussed. As result, it shown prepared can be promising substitute product Mo.
