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 66MeV using the stacked-foil technique. New data are presented for 89m,89gNb, 90(m+g)Nb, 91mNb, 92mNb, 95m,95gNb, 96Nb, 86Zr, 87(m+g)Zr, 88Zr, 89(0.94m+g)Zr, 95Zr, 85m,85gY, 86m,86(0.99m+g)Y, 87m,87(0.984m+g)Y, 88Y, 90mY, 91mY 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 70MeV, as compiled in the TENDL-2013 library. For a number of short-lived radionuclides, i.e., 85mY, 85gY, 86mY, 90mY, 91mY and 87(m+g)Zr, the present experimental cross sections are likely the first to be reported for their formation in natZr+p.
