Velocities of the fragment pairs from thermalneutron-induced fission of U/sup 233/, U/sup 235/, and Pu/sup 239/ have been measured by a time-of-flight method. The primary masses and energies of the fragments have been determined from the conservation of mass number and momentum. These results are compared with previous fission-fragment-mass and -energy measurements. A decrease of the total kinetic energy near the symmetric mode is observed, which is in agreement with previous double-ionization-chamber measurements. The intrinsic energy spread for mass-97 fnagments was found to be 8.l t 1.6% with a 95% confidence interval. (auth)
