Description

Neutron multiplicity measurements have been performed for reactions induced by ≅ 30 A.MeV 40Ar, 84Kr and 208Pb beams impinging on very heavy targets (197Au, 238U, 232Th). These neutron multiplicities have been measured in a 4π Gd loaded liquid scintillator neutron detector in coincidence with charged products as well as in single mode. The simultaneous determination of neutron and light charged particle multiplicities makes possible an evaluation of the average excitation energy stored in the hot system. (author) 8 refs., 6 figs
