Abstract

The energy spectra of α-particles emitted in the 171Yb(n, α)168Er and 173Yb(n, α)170Er reactions have been measured at the two neutron energies 14.12 and 18.18 MeV. The results have been analysed in terms of Hauser-Feshbach, pre-equilibrium and knock-on models. The experimental data can be described assuming the existence of preformed α-like structures in target nuclei and the processes involving only a few degrees of freedom.
