Abstract

Legendre moments of a double-differential Doppler-broadened elastic neutron scattering cross section on ²³⁸U are computed near the 6.67 eV resonance at temperature T = 10³ K up to angular order 14. A covariance matrix of these Legendre moments is computed as a functional of the covariance matrix of the elastic scattering cross section. A variance of double-differential Doppler-broadened elastic scattering cross section is computed from the covariance of Legendre moments.
