Ternary fission in the reaction 12C+232Th at Elab = 22AMeV reveals evidence for dynamical decay. The relative emission probability of intermediate-mass fragments (IMF: 3Z20) as a function of the initial excitation of the composite system is examined. While IMFs emitted pre-scission exhibit behavior consistent with statistical emission, near-scission IMFs, characterized by unique angular and energy distributions, clearly exhibit a behavior consistent with dynamical decay.
