Abstract

A method for representing a neutron spectrum in the thermal range as a superposition of a Maxwellian equilibrium neutron spectrum with a temperature equal to that of the moderator and a Maxwellian quasi-thermal nonequilibrium neutron spectrum is proposed. A method for representing the reactor spectra in the energy range of epithermal neutrons as a superposition of five to seven partial Maxwellian equilibrium spectra of elastically scattered neutrons was studied.
