Abstract :
Cross sections for (n, 2n)·(n,p) and (n, α) reactions have been measured on some rare-earth isotopes at 14.7±0.2 MeV using the activation technique. Data are reported for the following reactions: 154Sm(n,2n) 153Sm, 162Er(n, 2n) 161Er, 168Yb(n, 2n) 167Yb, 174Hf(n, 2n) 173Hf, 176Hf(n, 2n) 175Hf, 142Ce(n, p) 142La, 144Sm(n, p) 144Pm, 148Sm(n, p) 148mPm, 148Sm(n, p) 148gPm, 150Sm(n, p) 150Pm, 160Dy(n, p) 160Tb, 162Dy(n, p) 162Tb, 163Dy(n, p) 163Tb, 166Er(n, p) 166gHo, 167Er(n, p) 167Ho, 168Er(n, p) 168Ho, 174Yb(n, p) 174Tm, 150Sm(n, α) 147Nd, 152Sm(n, α) 149Nd, 154Sm(n, α) 151Nd, 153Eu(n, α) 150Pm, 159Tb(n, α) 156Eu, 162Dy(n, α) 159Gd, 164Dy(n, α) 161Gd, 168Er(n, α) 165Dy, 169Tm(n, α) 166gHo, 178Hf(n, α) 175Yb, 180Hf(n, α) 177Yb.
