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

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