A new method to determine compound nuclear lifetimes at high excitation energies is proposed and applied to the system C-12(Si-28, alpha)Ar-36 at two different bombarding energies, 190 and 277 MeV. The alpha particle spectra show a structure which directly reflects the fluctuating behavior of the first de-excitation step. Coherence widths and thus lifetimes for the nucleus Ar-36 were obtained via a correlation function analysis. The results at low excitation energies are consistent with standard statistical models while the result at high excitation energy is compatible with a theoretically predicted change of the level density parameter.
