The common cathode contained the sample of 3308900100013 235U. The grid-cathode and grid-collector distances 3308900100014 were 2.8 and 0.6 cm respectively. The two collectors 3308900100015 had thin aluminium windows of 2 mg/cm2 thickness at 3308900100016 their centres. The chamber was filled with a gas 3308900100017 mixture of argon (95 %) and methane (5%) to a 3308900100018 pressure of 92 cm of mercury to stop the fission 3308900100019 fragments in the cathode-grid region. 3308900100020 (SOLST) Behind the ionization chamber two 3308900100021 semiconductor detectors with depletion depth of 500 3308900100022 um and area of 2 cm2 were mounted to detect the LRAs 3308900100023 emitted in fission. 3308900100024 METHOD (COINC) Alpha particles were measured in coincidence 3308900100025 with fission fragments. 3308900100026 INC-SOURCE (REAC) Neutron flux 3x10E+7 n/cm2.s 3308900100027 ANALYSIS Calibration constants for the conversion of collector 3308900100028 and grid pulse heights into energy and angle of the 3308900100029 fission fragments were obtained using binary data. 3308900100030 The energy of the fission fragments were converted 3308900100031 into mass using the momentum and mass conservation 3308900100032 relations. The most probable values and the standard 3308900100033 deviations of the energy distributions are extracted 3308900100034 as a function of mass of heavier fission fragment. 3308900100035 PART-DET (A,FF) Alpha and fission fragments 3308900100036 ERR-ANALYS No information is given. 3308900100037 HISTORY (20161130C) Compiled by G.
