✦ Synopsis

New experimental cross sections are presented for 90 Zr(n, α) 87m Sr, 90 Zr(n, x) 89m Y, 90 Zr(n, p) 90m Y, 90 Zr(n, 2n) 89 Zr, 90 Zr(n, 2n) 89m Zr, 91 Zr(n, nα) 87m Sr, 91 Zr(n, x) 90m Y, 91 Zr(n, p) 91m Y, 92 Zr(n, x) 91m Y, 92 Zr(n, p) 92 Y, 94 Zr(n, α) 91 Sr, 94 Zr(n, x) 93 Y and 94 Zr(n, p) 94 Y reactions. These have been obtained with the activation technique using gamma-ray spectrometry and irradiations at the IRMM Van de Graaff laboratory. The new data were obtained in the energy range from 14 to 21 MeV. In nearly all cases this work provides the first data above 15 MeV and for the 92 Zr(n, x) 91m Y and 91 Zr(n, nα) 87m Sr reactions no earlier data were reported. The experimental results are compared with model calculations using the TALYS code to obtain a first indication of the impact of the new data on modeling of n + Zr reactions.
