Abstract
An array consisting of six neutron detectors has been constructed for measu rement of neutron multiplicities in heavy ion reactions. The measurements a re reported to demonstrate that. even with a modest array of six neutron de tectors, it is possible to infer unambiguously the neutron multiplicity (up to M = 4) of the reaction channel from the neutron fold distribution obtain ed in coincidence with gamma-rays, if the array is calibrated with known re action channels. The neutron multiplicity for the 991 keV gamma-ray produce d in the two heavy ion reactions Cs-133(C-12,C-13, xn) has been determined from this set-up-indicating that it deexcites levels in Pm-142. This is in agreement with the excitation function measurements for the same reactions. (C) 2000 Elsevier Science B.V. All rights reserved.
