The theories proposed by various authors for the explanation of the apparently anomalous small-angle elastic scattering of fast neutrons by238U nuclei  are reviewed. The problem is then considered by questioning the validity of the model and the assumptions which give rise to the anomalous discrepancy between the predictions and the experimental data. The measurement of the angular distribution of 14.7 MeV neutrons scattered elastically by uranium is reported. In the evaluation of the experimental data the inelastic contribution is taken into account as a consequence of bad energy resolution. The analysis of the scattering data in terms of the optical model does not show the occurrence of any anomaly.
