In the present study, we have simulated the central reactions of nearly symmetric and asymmetric systems over the entire periodic table for different values of energies using QMD model as event generator. These reactions are simulated for the different equations of state, nn cross-sections and different widths of Gaussians. We have observed that the multiplicity of IMFs shows a rise and fall with increase in beam energy in the center-of-mass frame as already predicted experimentally/theoretically. We have also studied the mass dependence of peak Ec.m. and peak . It has been observed that peak Ec.m. increases linearly with system mass whereas a power law dependence has been observed for peak IMFs with tau \approx 1.0. Our calculations using hard EoS along with cugnon cross-section and MSTB method are in good agreement with experimental data. Similar power law dependence is also observed for various fragments.
