Abstract

Events with fragment multiplicities up to eight have been detected with a large detector array in Pb + Au reactions at 29 MeV/u. All collisions show a binary character irrespective of a possible further disassembly of the two highly excited primary partners. For the most violent collisions, dissipative orbiting is observed as well as full energy damping corresponding to excitation energies as high as 6 MeV/u.

      Before discussing residue isoscaling and N/Z equilibration, we will examine the characteristics of residue velocities and the information on excitation energy that they can provide. It is well known that peripheral reactions between massive nuclei around the Fermi energy [17] proceed via a deep-inelastic transfer mechanism involving substantial nucleon exchange [13,22,23]. This mechanism is responsible for the creation of highly excited primary products that deexcite to produce the observed fragments.
