Abstract

Two-fragment correlation functions observed in central collisions of Ar36+197Au at E/A=50 MeV are compared to many-body trajectory calculations. For the present reaction, ambiguities between source size and lifetime can be reduced by employing directional emission cuts and describing observed differences between longitudinal and transverse correlation functions. For fragments emitted above the Coulomb barrier, E/A≥6 MeV, many-body Coulomb-trajectory calculations with a surface emission model indicate emission from an extended source of short lifetime.
