THE KINETIC ENERGY OF THE FISSION FRAGMENTS AND THE LONG-RANGE /cap alpha/- PARTICLES IN THE TERNARY FISSION OF U$sup 23$$sup 5$ (in Russian)
Groups of alpha particles having average energies of 10.6, were counted by using different thicknesses of aluminum foil. The relative number of ternary fission events to binary fission events is tabulated for the four groups of alpha particle energies. The energies of the fission fragments from ternary fission were measured by a multi-channel amplitude analyzer. The total decreases in energy of the light and heavy fission fragments DELTA E/sub l/ and DELTA E/ sub h/ are tabulated for the four groups of alpha -particle energies. The total decrease in energy of the fission fragments ( DELTA E/sub t/) is 10.9 Mev for an average E/sub alpha / of 10.6 Mev. 15.0 Mev for an E/sub alpha / of 18.4 Mev, 14.S Mev for an E/sub alpha / of 20.3 Mev, and 15.5 plus or minus 1.6 Mev for an E/sub alpha / of 24.0 Mev. The results show that the total kinetic energy during ternary fission increases with increasing energy of the long-range alpha particle and can significantiy exceed the total kinetic energy of binary fission. The mass ratio of the fission fragments (M/sub 2/M/sub 1/) remains constant at 1.5 for various energies of the long-range alpha particles. (TTT)
