We here study fragmentation using simulated annealing clusterization algorithm (SACA) with binding energy at a microscopic level. In an earlier version, a constant binding energy (4 MeV/nucleon) was used. We improve this binding energy criterion by calculating the binding energy of different clusters using modified Bethe-Weizsäcker mass (BWM) formula.We also compare our calculations with experimental data of ALADiN group. Nearly no effect is visible of this modification. * rkpuri@pu.ac.in

Using the quantum molecular dynamics model, we aim to investigate the emission of light complex particles, and degree of stopping reached in heavy-ion collisions. We took incident energies between 50 and 1000 MeV/nucleon. In addition, central and peripheral collisions and different masses are also considered. We observe that the light complex particles act in almost similar manner as anisotropic ratio. In other words, multiplicity of light complex particles is an indicator of global stopping in heavy-ion collisions. We see that maximum light complex particles and stopping is obtained for heavier masses in central collisions.
