Description

Abstract: In this study, we analyze the experimental data from heavy-ion collision (HIC) using 40Ca and 48Ca beams at 140 MeV/u impinging on 58Ni and 64Ni targets. The experimental set up includes a charged particle array HiRA10 and the neutron wall array, LANA. From the charged particles, we construct coalescence invariant ratios of pseudo-neutrons and protons as a function of transverse momentum. The data is compared with nuclear transport model predictions using Bayesian analysis technique to infer the correlations of nucleon effective masses.
