Light fragment emission correlated with large transverse momentum protons in 94 mev/u 16O induced reactions

Abstract

Angular, multiplicity and velocity distributions as well as azimuthai asymmetries of light fragments ( Z = 1 and 2) correlated with large transverse momentum protons detected at 90° have been measured in 16 O + 27 Al collisions at 94 MeV/u. Data are compared with a model based on the standard high-energy fireball geometry coupled with the Weisskopf theory of evaporation. Reasonable agreement is achieved with the exception of some discrepancies which could arise either from the absence of specific intermediate-energy corrections or from a non-statistical process.
