Two-particle correlation functions, involving protons, deuterons, tritons, and alpha-particles,
have been measured at very forward angles (0.7° <= thetalab <= 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. |
