Probable Level Densities and Radiative Strength Functions of Dipole   gamma-Transitions in 57Fe Compound Nucleus
  From the published results of experimental research of 56Fe(n,2gamma) reaction carried out in Budapest, the values of the most probable densities of cascade intermediate levels with 1/2, 3/2 spin and radiative strength functions of cascade E1 and M1 transitions in 57Fe compound nucleus have been determined. These results correspond to analogous data for other nuclei studied by us and contradict to predictions of conventional models.
