Abstract
The partition of excitation energy between fragments from reactions of 8 A · MeV116Sn with48Ti was studied. The experimental setup rendered possible the unambiguous identification of primary fragments up to total excitation energies of 50 MeV. Neutron mulitplicities of both projectile-like and target-like fragments were experimentally determined as a function of excitation energy. Comparison of these quantities with the results of numerical calculations of sequential decay including rotation of the fragments allowed the determination of excitation energy partition and the associated fluctuations.
