Abstract : New techniques for computing intensity distributions from atomic arrangements with defects in periodicity were applied to a variety of models in an attempt to reproduce in detail the diffuse neutron diffraction pattern of a Zr-20 wt. % Nb alloy quenched from 1273K. The model which succeeds is described, and its kinematic intensity sum is derived. The resultant computed diffuse intensity distribution is compared with experiment. (Author)
