“…7. In this figure we report the measured production cross sections of different tin isotopes in the reaction 129 Xe on aluminum at 790 A MeV [10] and 50 A MeV [11]. According to these data the higher energies enhance the production of neutron-rich residues.…”

“…Pioneering studies by Bazin, et al [3], Faure-Ramstein, et al [4], Pfaff, et al [5] and Hanold, et al [6] have shown the utility of this approach in studying the heavy reaction products from Kr+X and Xe+X mass asymmetric collisions at intermediate energies. In a previous paper [7], we reported the results of a similar study of the reaction of 20 MeV/nucleon 197 Au with the light nuclei 12 C and 27 Al.…”

The yields and velocity distributions of heavy residues and fission fragments from the reaction of 20 MeV/nucleon 197 Au + 90 Zr have been measured using the MSU A1200 fragment separator. A bimodal distribution of residues is observed, with one group, resulting from peripheral collisions, having fragment mass numbers A=160-200 while the other group, resulting from "hard"collisions, has A=120-160. This latter group of residues can be distinguished from fission fragments by their lower velocities. A model combining deep-inelastic transfer and incomplete fusion for the primary interaction stage and a statistical evaporation code for the deexcitation stage has been used to describe the properties of the product distributions.

“…It nevertheless appears that the participant-spectator scenario starts to play role at energies above 50 AMeV for very asymmetric projectiletarget combinations. Also in this domain, in particular for reactions 129 Xe+ 27 Al at 50 AMeV [9] and 78 Kr+ 58 Ni at 75 AMeV [10], there are signals of the neutron loss (dynamical emission) preceding the thermal equilibration of the massive projectile-like fragment. Such effect is observed in the case of proton-rich projectile-like fragments while in neutron-rich cases it may be overshadowed by intense statistical emission of neutrons.…”
