COMPLETE ENERGY DAMPING IN 29 MEV NUCLEON PB+AU 2-BODY FINAL-STATE REACTIONS/

Decay products emitted in highly dissipative Pb+Au reactions at 29 MeV /nucleon have been detected using a large area array. Multiplicities o f fragments as large as 8 have been detected with a sizeable cross sec tion. The m-fragment exit channels are fully compatible with the forma tion of a transient excited dinuclear system formed in damped collisio ns. The excitation energy function shows that fully damped collisions are achieved even for m = 2 indicating that heavy nuclei are able to s ustain high excitation energy and end up as evaporation residues.
