# RELATION BETWEEN NEUTRON SCATTERING IN POLYCRYSTALS AND SPECIFIC HEAT

## Abstract

The crystalline frequency spectrum entering into the cross section for inelastic coherent scattering of thermal neutrons in polycrystals is linked with the lattice specific heat at constant volume and can be determined from experimental values of the specific heat. However, such a procedure is subject to errors of considerable magnitude and are difficult to control. It is possible to do better with the characteristics of neutron scattering which depend on integrals over the frequency spectrum, such as the total cross section for inelastic scattering. This procedure is demonstrated in calculating the quantity sigma , which for very cold neutrons coincides with the total coherent cross section. (M.H.R.)
