Özet

The neutron spectrum from the (55)mn(d,n)Fe-56 reaction has been measured at E-d = 7 MeV. The level density of Fe-56 obtained from neutron evaporation spectrum has been compared to the level density obtained from Oslo-type Fe-57(He-3, alpha gamma)16 Fe experiment [1]. The good agreement supports the recent results [1, 2] including the low-energy enhancement in the gamma-strength function for iron isotopes. The new level density function allowed us to investigate an excitation energy dependence of this enhancement, which is shown to increase with increasing excitation energy.
