EXCITATION-ENERGY DIVISION IN HEAVY-ION REACTIONS

The excitation energy of the primary products from the reaction Fe-56 on Ho-165 at 672 MeV was determined by the kinematic coincidence techn ique. The Fraction of the rural excitation energy of the system stored in the projectilelike fragment was found to decrease with increasing energy loss. However, thermal equilibrium is not reached, even at the highest energy damping. A small correlation between excitation energy partition and reaction exit channel was observed. Monte Carlo simulati ons of the present experiment confirmed that some of this correlation is due to the finite resolution of the measured parameters.
