Measurement Of Average Neutron Energies For (o, n) Neutron Sources (open access)

Measurement Of Average Neutron Energies For (o, n) Neutron Sources

A method is presented for measuring the average energy of the neutrons from a source. The attenuation of the neutrons by polyethylene is measured by the use of a long counter in good geometry. The attenuation length is a sensitive function of the neutron energy. The average neutron energies from several (o, n) sources have been measured and agree well with values obtained by other techniques.
