Abstract
The coherent neutron scattering intensities from five phonon modes in naphthalene have been measured at twenty four points in reciprocal space. These intensities are determined by a set of eigenvectors, and a fit to these intensities has been obtained by altering the eigenvectors iteratively. Significantly the best result has been obtained starting from eigenvectors derived from a model calculation, which were found to be close to the final result. This supports our method of assigning neutron scattering results by a comparison with model calculations.Keywords
