Detection of three 4156400100026 particles in coincidence makes it possible to 4156400100027 reconstruct the primary neutron energy in the 4156400100028 n+d -> p+n+n reaction and obtain data on the reaction 4156400100029 yield in a wide range of neutron energies, determined 4156400100030 only by the statistics of the experiment. 4156400100031 DETECTOR (TELES,SCIN) dE-E telescope consisting of two fast 4156400100032 plastic scintillation detectors.
