Heavy ion reaction studies of NbAu at E/A = 50, 75 and 100 MeV

We report on measurements of the system Nb+Au at incident energies of E/A = 50, 75 and 100 MeV made with a large solid angle, large dynamic range gas-scintillator array. We observe that in these reactions fission is the result of peripheral collisions. Somewhat less peripheral reactions result in heavy residues which do not undergo fission. More central reactions result in high multiplicities of light particles and intermediate mass fragments. Correlations between fragments, energetic light charged particles, and forward moving projectile-like fragments are presented to support these observations. (orig.)
