✦ Synopsis

Light charged particle, (Z = 2), and intermediate-mass fragments, (2 < Z < 8), emitted in the mid-rapidity region were studied as a function of collision violence in 124 Sn, 124 Xe + 124 Sn, 112 Sn reactions at 28 MeV/nucleon. With increasing centrality, the heavier 6 He isotope is found to be emitted closer to mid-rapidity than the lighter 3 He isotope. The emission becomes increasingly favorable for particles with higher charge, Z, indicating mid-rapidity region to be not only neutron rich, but also a rich source of heavy fragment (cluster) formation.
