Correlation functions of light charged particles from projectile-like fragment source in E/A=44 and 77 MeV 40Ar + 27Al collisions

Two-particle correlation functions, involving protons, deuterons, tritons, and α-particles, have been measured at very forward angles (0.7°⩽θlab⩽7°), in order to study projectile-like fragment (PLF) emission in E/A = 44 and 77 MeV 40Ar + 27Al collisions. The observed correlations are similar for the two reactions at E/A=44 and 77 MeV, except for peaks originating from resonance decays, which are larger at the lower bombarding energy. Particle-velocity gated correlation functions are presented, and possible implications on the time sequence of the light charged particles, emitted from the PLF, are discussed.
