| Popis: |
Excitation functions have been measured for complex fragments with Z=3–15 emitted in collisions of E/A=60, 80 and 100 MeV 14 N ions with targets of natAg and 197Au. The results are analyzed in terms of a three-source model: projectile fragmentation, non-equilibrium emission from the composite system, and statistical decay of an equilibrated heavy residue. Enhanced heavy fragment production is found for reactions with the natAg target above E/A⩾60 MeV. Above E/A≅50 MeV the ratio of equilibrium to non-equilibrium cross sections is found to be nearly independent of bombarding energy. Fit-parameter systematics are presented. |
