Impact parameter and source selected correlation functions with the 4π multidetector INDRA — •David Gourio — Planckstr. 1, 64291 Darmstadt

Correlation functions of light charged particles have been studied with both projectile-like source and impact parameter selections. The system Xe+Sn at E_inc=45 and 50 AMeV has been measured using the 4π multidetector INDRA as an event and source selector as well as a particle correlator. The extracted emission times for protons and deuterons and the emission time differences between both give indications for a reasonable chronology. The very short emission times for protons might indicate possible contributions from a fast and preequilibrium process included in the forward source selection, as predicted by the dynamical model Landau-Vlasov.
