Dissipative processes in light-heavy-ion-induced reactions and their time scales

Strongly damped exit channels are identified in light-heavy-ion-induced reactions ({sup 9}Be, {sup 10,11}B, {sup 18}O+{sup 10,11}B at {ital E}{sub lab}{le}5 MeV/ nucleon), and their time scales are inferred from the isotropy of the angular distributions. These light compound systems seem able to reach statistical equilibrium within a fraction of a revolution of the dinuclear intermediate configuration. No simple correlation among the inelasticity of the process, mass transferred and decay angle'' is perceived.
