Differential cross sections for the elastic scattering of 14.6 MeV neutrons from /sup 9/Be, C, /sup 27/Al, Fe, /sup 59/Co, /sup 89/Y, /sup 93/Nb, In, /sup 140/Ce, /sup 181/Ta, /sup 197/Au, /sup 208/Pb, and /sup 209/Bi have been measured using a time-of-flight facility. The measured cross sections cover the angular range from 9.2/sup 0/ to 159/sup 0/. Calculations have been carried out using two local microscopic optical potentials, based on the work of Jeukenne, Lejeune, and Mahaux, and of Brieva and Rook. Reasonably good agreement with the measurements is found over the whole mass range, with the Jeukenne-Lejeune-Mahaux potential giving systematically better agreement with the data. The quality of the results with the Jeukenne-Lejeune-Mahaux potential compares well with that obtained from phenomenological optical model calculations using global parameters.
