The Mn55(d,n)Fe56 differential cross section is measured at Ed=7 MeV. The Fe56 level density obtained from neutron evaporation spectra is compared to the level density extracted from the Fe57(He3, αγ)Fe56 reaction by the Oslo-type technique. Good agreement is found between the level densities determined by the two methods. With the level density function obtained from the neutron evaporation spectra, the Fe56 γ-strength function is also determined from the first-generation γ matrix of the Oslo experiment. The good agreement between the past and present results for the γ-strength function supports the validity of both methods and is consistent with the low-energy enhancement of the γ strength below ∼4 MeV that was first discovered by the Oslo method in iron and molybdenum isotopes.
