【 摘 要 】

Excitation functions for the formation of various radionuclides of Nb, Zr, Y and Sr in proton-induced reactions on natural zirconium were measured up to 66 MeV using the stacked-foil technique. New data are presented for Nb-89m,Nb-89g, Nb90(m+g), Nb-91m, Nb-92m, Nb-95m,Nb-95g, Nb-96, Zr-86, Zr87(m+g), Zr-88, Zr89(0.94m+g), Zr-95, Y-85m,Y-85g, Y-86m,Y-86(0.99m+g), Y-87m,Y-87(0.984m+g), Y-88, Y-90m, Y-91m and Sr85(0.87m+g). The experimental results are compared with the available literature data as well as the evaluated theoretical predictions by means of the TALYS code, up to 70 MeV, as compiled in the TENDL-2013 library. For a number of short-lived radionuclides, i.e., Y-85m, Y-85g, Y-86m, Y-90m, Y-91m and Zr87(m+g), the present experimental cross sections are likely the first to be reported for their formation in Zr-nat + p.
