Description

Damped reactions induced by very heavy ions on heavy targets have been studied. Strong correlations of experimental observables with the kinetic-energy loss suggest a continuous evolution of the reaction mechanism from quasi-elastic to strongly damped collisions. These correlations are employed to deduce experimental deflection functions, reaction times and transport coefficients for nucleon exchange. The time scale provided by the statistical nucleon exchange process is applied to study the energy dissipation mechanism in terms of a diffusion model and a one-body dissipation mechanism. The bombarding energy dependence of the experimental correlations is discussed. (orig.)

Abstract (German)

Gedaempfte Reaktionen, induziert durch sehr schwere Ionen in schweren Targets, wurden untersucht. Dabei zeigen sich starke Korrelationen zwischen den experimentell beobachteten Groessen und dem kinetischen Energieverlust, was eine kontinuierliche Entwicklung des Reaktionsmechanismus von quasi-elastischen bis zu stark gedaempften Stoessen vermuten laesst. Diese Korrelationen werden zur Ableitung experimenteller Ablenkungsfunktionen, Reaktionszeiten und Transportkoeffizienten fuer Nukleonenaustausch verwendet. Die Zeitskala des statistischen Nukleonenaustauschprozesses wird zur Untersuchung des Energiedissipationsmechanismus im Rahmen eines Diffusionsmodeels und eines Einkoerper-Dissipationsmodells benutzt. Die Abhaengigkeit der experimentellen Korrelationen von der Einschussenergie wird diskutiert. (orig.)
