IMF-IMF azimuthal correlations as a tool to probe reaction dynamics in $^{36}Ar$ + $^{48}$Ti at 45 A MeV

IMF-IMF azimuthal correlation functions have been measured in 36Ar + 48Ti collisions at 45 A MeV. The experimental data as well as the events generated with IQMD were sorted with respect to impact parameter and the analysis was restricted to the mid-rapidity region. We find strong anisotropies and asymmetries in the measured correlation functions, which cannot be described by independently emitted particles. The measured correlation functions are, however, well reproduced by IQMD model calculations, although decay of a small mid-rapidity source cannot be excluded experimentally.
