Activation cross-sections for (158)Dy(n,p)(158)Tb, (156)Dy(n,alpha)(153)Gd and (160)Dy(n,p)(160)Tb reactions induced by neutrons at 14.7MeV.

摘要

The cross-sections for the (158)Dy(n,p)(158)Tb, (156)Dy(n,alpha)(153)Gd and (160)Dy(n,p)(160)Tb reactions induced by 14.7MeV neutrons were measured in this work and calculated by a previously developed formula. Measurements were corrected for gamma-ray attenuations, random coincidence (pile-up), dead time and fluctuation of neutron flux. Nuclear model calculations using the code HFTT, which employs the Hauser-Feshbach (statistical model) and exciton model (precompound effects) formalisms, were undertaken to describe the formation of the products.
