Data on elastic scattering of 96 MeV neutrons from 56Fe, 89Y, and 208Pb in the angular interval 10-70° are reported. The previously published data on 208Pb have been extended, as a new method has been developed to obtain more information from data, namely to increase the number of angular bins at the most forward angles. A study of the deviation of the zero-degree cross section from Wick's limit has been performed. It was shown that the data on 208Pb are in agreement with Wick's limit while those on the lighter nuclei overshoot the limit significantly. The results are compared with modern optical model predictions, based on phenomenology and microscopic nuclear theory. The data on 56Fe, 89Y, and 208Pb are in general in good agreement with the model predictions.
