Popis: The yields of intermediate-mass fragments from the reactions 14N + 159Tb/natAg/ natCu have been measured at 22 MeV/u. A complete set of double-differential cross sections d 2 σ/ d E d Ω ranging from 15° to 165° and with low-energy thresholds has been obtained. The evolution of the intermediate-mass spectra from quasi-elastic via more dissipative reactions towards evaporation can be followed and has been compared with a phenomenological random-walk model. For the system studied, the results suggest damped collisions as the only source for the emission of intermediate-mass fragments in the dissipative regime.
