Excitation functions and thick-target recoil ranges for radioactive nuclei produced in {sup 20}Ne bombardment of natural copper over a 8--46-MeV/nucleon energy range have been measured using the activation technique. From the experimental data the mass yields, charge distributions, total reaction cross section, average and maximum recoil velocities, linear momentum transfer, and excitation energies were deduced. These quantities are compared with similar data on copper obtained using {sup 14}N projectiles by our group and lighter ions in other works. In {sup 20}Ne-induced reactions the maximum linear momentum transfer in central collisions is reached at a bombarding energy of 11 MeV/nucleon and is equal to 2.8 GeV/{ital c}. At the same projectile energy the excitation energy of heavy prefragments produced in these collisions reached the value of about 2 MeV/nucleon. For higher bombarding energies the excitation energy per nucleon slightly increases up to about 2.5 MeV/nucleon. The distribution of the recoil velocity deduced from the present experiment at 30 MeV/nucleon bombarding energy seems to be in contradiction with the results of a Landau-Vlasov simulation of the reaction dynamics.
