In this paper we briefly discuss about a novel application of the IMF- IMF correlation function in the physics case of heavy projectile-like (PLF) binary fission-like massive splitting in heavy ion collisions at Fermi energy. In particular, results are shown for the reverse kinematics reaction 124Sn+64Ni at 35 AMeV that has been investigated by using the forward part of CHIMERA multi-detector. Transport CoMD simulations are compared with the data. The main analysis was performed as a function of the charge asymmetry of the decay channel. The coexistence of dynamical and statistical components as a function of the charge asymmetry of the binary breakup is clearly evidenced. We show that the IMF-IMF correlation functions, when coupled with transport calculations, can be used to pin down the timescale of the fragments production and consequently the relevant ingredients of the in medium effective interaction. Efforts are being planned to extend the method to different reaction mechanisms and nuclear systems and, also, to compare the data with different transport theory simulations.
