Paper Abstract

A method to determine an effective energy for beams with energies less than 100 meV is proposed using measured transmittances for neutron beams with continuum spectra. Effective energies for unknown beams were determined from a ratio of effective total macroscopic cross section of Ti to that of Pb. The effective energies are calibrated using mean energies from known neutron spectra of a thermal-neutron and two cold-neutron beams generated from research reactors. Results are summarized in a table and maximum systematic uncertainties of effective energies are estimated to be 14% for thermal and 27% for cold neutron regions.
