TARGET RESIDUES FROM THE INTERACTION OF COPPER WITH 20-46 MEV NUCLEONC-12 IONS/

Target residues from the interaction of copper with 20-46 MeV/nucleon C-12 ions have been studied using the thick-target, thick-catcher reco il technique. From the experimental data the excitation functions, iso baric yield distributions, mass yield distributions, linear momentum t ransfer and excitation energy were deduced. The experimental mass yiel d distributions can be reproduced by the GEMINI code for statistical b inary decay, following a calculation with the fireball model. The line ar momentum transfer per projectile nucleon in central collision attai ns a maximum value of 155 MeV/c at 27.5 MeV/nucleon. At the same proje ctile energy the excitation energy of the composite system produced fr om these central collisions is between 2.5-3 MeV/nucleon. The experime ntal results have been compared with those given in previous publicati ons.
