Abstract :
An array consisting of six neutron detectors has been constructed for measurement of neutron multiplicities in heavy ion reactions. The measurements are reported to demonstrate that, even with a modest array of six neutron detectors, it is possible to infer unambiguously the neutron multiplicity (upto M=4) of the reaction channel from the neutron fold distribution obtained in coincidence with γ-rays, if the array is calibrated with known reaction channels. The neutron multiplicity for the 991 keV γ-ray produced in the two heavy ion reactions 133Cs(12,13C,xn) has been determined from this set-up-indicating that it deexcites levels in 142Pm. This is in agreement with the excitation function measurements for the same reactions.
