Excitation functions of natZr + p nuclear processes up to 70 MeV: New measurements and compilation

Abstract 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 89m,89g Nb, 90(m+g) Nb, 91m Nb, 92m Nb, 95m,95g Nb, 96 Nb, 86 Zr, 87(m+g) Zr, 88 Zr, 89(0.94m+g) Zr, 95 Zr, 85m,85g Y, 86m,86(0.99m+g) Y, 87m,87(0.984m+g) Y, 88 Y, 90m Y, 91m Y and 85(0.87m+g) Sr. 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., 85m Y, 85g Y, 86m Y, 90m Y, 91m Y and 87(m+g) Zr, the present experimental cross sections are likely the first to be reported for their formation in nat Zr + p.
