The ratio of the neutron induced fission cross-sections of /sup 238/U and /sup 235/U have been measured in the energy range from 600 keV to 22 MeV using the time-of-flight method on the Harwell synchrocyclotron, at a nominal resolution of 0.5 ns/m. Fission fragments were detected in a gas scintillation chamber containing foils of each material mounted back-to-back and perpendicular to the incident beam. The measured cross-section ratio was normalized at 14 MeV to the ratio evaluated by Sowerby et al. The estimated standard deviation error in the ratio measurements is +-2/sup 1///sub 2/ percent. Comparison with other recent data shows reasonable agreement throughout most of the energy range. 3 figures, 1 table. (auth)
