文摘

Cross-sections for (n,2n), (n,p), (n,α), and (n,d*) (The expression (n,d*) cross section used in this work includes a sum of (n, d), (n, np) and (n, pn) cross sections) reactions have been measured on erbium isotopes at the neutron energies from 13.5 to 14.8 MeV using the activation technique in combination with high-resolution gamma-ray spectroscopy. Data are reported for the following reactions: 162Er(n,2n)161Er, 164Er(n,2n)163Er, 168Er(n,α)165mDy, 166Er(n,p)166gHo, 170Er(n,α)167Dy, 168Er(n,p)168m+gHo, 170Er(n,p)170gHo, and 170Er(n,d*)169Ho. The cross sections were discussed and compared with experimental data found in the literature, and with the comprehensive evaluation data in ENDF/B-VII.0 and l JEFF-3.1/A libraries.
