Abstract
High energy gamma-rays ( E-gamma > 35 MeV) have been measured in coincidenc e with heavy residues emitted in reactions induced by a 37 MeV/u Ar-36 beam on a Mo-98 target. The gamma-ray yield increases strongly with increasing linear momentum transfer indicating the importance of two-body collisions i n the transfer mechanism. The high energy gamma-ray multiplicity has been u sed to correlate the linear momentum transfer to the impact parameter. This correlation is compared to dynamical BNV simulations to show the essential role of two body nucleon-nucleon collisions at these bombarding energies. (C) 1998 Published by Elsevier Science B.V.
