Fragment-energy and specific-luminescence spectra from the fission of /sup 232/Th and /sup 238/U were measured by a two-dimensional display of coincident signals from a solid state detector and a thin-film organic scintillator detector. Symmetric-to-asymmetric fission ratios and peak-to-valley ratios were determined as a function of bombarding energy. Discontinuities in the ratio curves, observed in some previous experiments but not in others, were mapped out in detail. The major discontinuities were found to occur near fission thresholds.
