Reconstructed quasi-projectile source distributions as a probe of the nuclear equation of state

Products from the reaction of 45 MeV/A beams of S on targets of Sn were measured with the Forward Array Using Silicon Technology (FAUST) [1]. Charged particle identification and energy calibration of the array have been completed [2]. The design of the FAUST Array selects heavily against particles emitted from a target like source. For peripheral reactions, this allows for relatively straightforward definition of projectile like sources based on the total charge collected during a given event. For the investigation discussed here, projectile-like sources have been defined by selecting for events where the sum collected charge is equal to that of the incident sulfur beam (Z=16). Accepted events also must also be composed only of particles identified in both charge and mass. Given this event selection, quasi-projectile distributions are presented in terms of ΔNapp as defined below.
