A066600100022 METHOD (TOF) A066600100023 SAMPLE A Th-232 self-supporting target of 1.5 mg/cm**2 A066600100024 thickness was used. A066600100025 DETECTOR (TELES,SI,CSICR) Detector was the 8-PiLP device, with A066600100026 260 delta-E-E telescopes, consisting of two parts- A066600100027 the 'WALL' and the 'BALL'. Each telescope is made of a A066600100028 transmission type 300 mum thick Si detector followed byA066600100029 a CsI(Tl) crystal, 15 mm or 5 mm thick for the 'WALL' A066600100030 and the 'BALL'. The 'WALL' is a matrix of 11*11 A066600100031 telescopes. The 'BALL' consists of 6 rings of 18 A066600100032 telescopes each. A066600100033 The 'BALL' detectors were used to detect fission A066600100034 fragments as well as light charged particles. A066600100035 Two neutron detectors were operated in coincidence withA066600100036 the fission fragments. Neutron detectors are of A066600100037 cylindrical shape, 10 cm diameter and 5 cm thick, A066600100038 filled with NE213 liquid scintillator. A066600100039 Neutrons and gamma-rays were distinguished by a A066600100040 combination of time of flight and pulse shape A066600100041 discrimination techniques. A066600100042 ADD-RES (COMP).Dynamical model calculation. A066600100043 The pre-scission and post-scission neutron A066600100044 multiplicities are deduced to be 8.7+-2.0 and A066600100045 9.4 +-2.0, respectively. The corresponding A066600100046 multiplicity values for alpha particles are found A066600100047 to be 0.22 +-0.08 and 0.1+-0.03.
