Abstract:
We report on the study of the intensities of several gamma lines emitted after the inelastic scattering of
neutrons in 56Fe. Neutrons were produced via nuclear processes induced by cosmic muons in the
20 tons massive iron cube placed at the Earth’s surface and used as a passive shield for the HPGe
detector. Relative intensities of detected gamma lines are compared with the results collected in the
same iron shield by the use of the 252Cf neutrons. Assessment against the published data from neutron
scattering experiments at energies up to 14 MeV is also provided. It allowed us to infer the qualitative
information about the average energy of muon-created neutrons in the iron shield.
