SAMPLE Enriched (99.99%) U vacuum evaporated on the polyamide 4173800100021
foil of 35 microgram/cm2. The homogeneous U layer 4173800100022
thickness was 48 microg/cm2. The target was of 4173800100023
circular shape with 70 mm diameter, gold plated 4173800100024
(~20 microgram/cm2). 4173800100025

METHOD (TOF,COINC) The fission fragment kinetic energy, mass 4173800100035
and angular distribution has been investigated along 4173800100036
with prompt neutron time of flight and pulse shape 4173800100037
using a six channel synchronous waveform digitizer 4173800100038
with sampling frequency of 250 MHz and 12 bit 4173800100039
resolution.The signals were analyzed using digital 4173800100040
pulse processing algorithms, developed by authors. 4173800100041
About 10**6 neutron coincidences were registered. 4173800100042
