Neutron spectra from the ${}_{}{}^{156}{}_{}{}^{}\mathrm{Er}$ compound nucleus populated by ${}_{}{}^{12}{}_{}{}^{}\mathrm{-}$ and ${}_{}{}^{64}{}_{}{}^{}\mathrm{induced}$ reactions

Inclusive neutron spectra from the decay of ${}_{}{}^{156}{}_{}{}^{}\mathrm{Er}$ compound nucleus populated at ${\mathit{E}}_{\mathit{x}}$=47 MeV excitation energy by the ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$${+}^{144}$Sm and ${}_{}{}^{64}{}_{}{}^{}\mathrm{Ni}$${+}^{92}$Zr reactions have been measured. The neutron spectra from the ${}_{}{}^{64}{}_{}{}^{}\mathrm{induced}$ reaction are strongly contaminated by other reactions different from fusion evaporation so that inclusive spectra cannot be used to test nonstatistical or entrance channel effects in the compound nucleus decay.
