Heavy Fragments Emission from Highly Excited Nuclei

摘要

In the intermediate energy domain, the high amount of excitation energy and angular momentum deposited in the nuclei allow the emission of fragments heavier than the usual evaporation particles to have a significant cross section. The study of the properties characterizing the production of these fragments could be a good way to investigate the mechanisms which contribute to formation of hot nuclei and the limits for linear momentum and excitation energy deposited in the nucleus, as well as possible deformations related to these high temperatures. These phenomena might depend much on the center of mass energies and angular momenta. In order to analyse these entrance channel effects/sup 3/, we chose to study the following systems: Kr + C, Kr + Al, Kr + Ti at an incident energy of the Kr beam delivered by GANIL of 2216 MeV. 7 figs, 1 tab, 9 refs..
