Role of statistical fluctuations in the emission ofδelectrons from dissipative heavy-ion collisions

Energy spectra of {delta} electrons emitted in coincidence with deep-inelastic heavy-ion collisions are calculated within a Langevin Monte Carlo description using the surface-friction model. We investigate the effects that wipe out the originally expected oscillatory pattern of the spectra. Emphasis is placed on the role of statistical fluctuations in extracting interaction time distributions of deep-inelastic collisions from the measured {delta}-electron spectra. The calculations are compared to data for U+Au at 8.65 MeV/nucleon.
