EXCITATION-FUNCTIONS OF DEUTERON INDUCED NUCLEAR-REACTIONS ON TI-NAT UP TO 20-MEV FOR MONITORING DEUTERON BEAMS

Excitation functions were measured for nuclear reactions on natural Ti leading to the formation of the Sc-43,Sc-44m,Sc-44g,Sc-46,Sc-47,Sc-48 and V-48 isotopes up to 21 MeV deuteron energy using the stacked-foil technique. The measured excitation functions, the calculated thick ta rget yields and activity calibration functions for the thin layer acti vation technique have been compared with the earlier literature data. The investigation with respect to their potential application as monit or reactions showed that the reactions on Ti-nat could be recommended for monitoring deuteron beams, especially the Ti-nat(d,x)V-48 reaction , in the energy range from 3 up to 20 MeV. However, to clear up the di screpancies in the literature and to compare the results with other mo nitor reactions, additional measurements are required. (C) 1997 Elsevi er Science Ltd.
