Cross Sections and Spectra for the ⁵⁴Fe and ⁵⁶Fe (n,xp) and (n,xα) Reactions Between 8 and 15 MeV

Cross sections and spectra for the (n,xp) and (n,xα) reactions on targets of ⁵⁴Fe and ⁵⁶Fe are measured at 8-, 9.5-, and 11-MeV bombarding energies. The bulk of the spectra appears to be the result of compound nuclear reactions, based on their angular and emission energy dependence. A single set of level density parameters is deduced which fits not only these data but also the data recently obtained at 15 MeV. Very small (n,d) cross sections are found in this energy region.
