NEUTRON COMPTON-SCATTERING

Neutron Compton scattering measurements have the potential to provide direct information about atomic momentum distributions and adiabatic e nergy surfaces in condensed matter. First applied to measuring the con densate fraction in superfluid helium, the technique has recently been extended to study a variety of classical and quantum liquids and soli ds. This article reviews the theoretical background for the interpreta tion of neutron Compton scattering, with emphasis on studies of solids .
