Nuclear reactions cross sections (n, x) on dysprosium and ytterbium isotopes

Abstract

Cross sections of nuclear reactions 162,163Dy(n, x)162Tb, 163,164Dy(n, x)163Tb, 156Dy(n, 2n)155Dy, 158Dy(n, 2n)157(m+g)Dy, 166,167Er(n, x)166gHo, 170Er(n, p)170gHo were measured and presented for incident neutron energy (14.6 ± 0.2) MeV. The measurements were undertaken with neutron-activation technique. Samples of natural composition of above mentioned elements were irradiated with (d-t) neutrons. Instrumental gamma-ray spectra of induced activities were measured using HPGe detectors. The main sources of uncertainties for cross section values were considered and taken into account. Measured cross section for 162Er(n, p)162(m+g)Ho nuclear reaction is considered as original data. Theoretical calculations of excitation functions for all reactions in specified energy range were performed with TALYS-1.2 code.
