C252200100009 (M,14653001,H.C.Britt+,J,PR,129,2239,1963) The C252200100010 experimental techniques. C252200100011 INSTITUTE (1USALAS) C252200100012 FACILITY (CYCLO,1USALAS) C252200100013 DETECTOR (SIBAR) The two semiconductor detectors were mounted C252200100014 in a back-to-back arrangement at an angle of 90 C252200100015 degrees relative to the beam direction. C252200100016 SAMPLE The targets used had areal densities of 10-30 C252200100017 microg/cm2 and were prepared by evaporation onto C252200100018 nickel backings of 50-100 microg/cm2. C252200100019 METHOD (TOF) Measurements have been made of the kinetic C252200100020 energies of coincident- fission fragment pairs C252200100021 emitted in the 22.1-, 25.7-, and 29.5-MeV He4-induced C252200100022 fission of 230Th, 232Th, and 233U to determine the C252200100023 mass and total kinetic-energy distributions of the C252200100024 fragments. From a comparison of the mass C252200100025 distributions obtained from double-energy C252200100026 measurements with the mass distributions obtained C252200100027 from double-velocity time-of-flight measurements, it C252200100028 is possible to deduce the average number of prompt C252200100029 neutrons emitted as a function of the fragment mass. C252200100030 In the energy measurements the solid angle subtended C252200100031 by the detectors was approximately 9x10**-2 sr.
