• Abstract A comparative study of α-decay channel from the composite systems 144Nd* and 148Sm* populated via n-induced reactions- n+ 143 Nd and n+ 147 Sm, is done at E b eam=5.0 MeV. The study proceeds through the Dynamical Cluster-decay Model (DCM) as suggested by an experiment performed by Gledenov et al. at Peking University, China. An attempt is made to do a theoretical investigation of decay profiles of 144 Nd* and 148 Sm* to analyze the effect of temperature, neck-length and angular momentum state of the hot-rotating system at common beam energy. The results are exhibited in the form of variations in fragmentation structure and the barrier modification effects that are illustrated from the barrier penetration profiles. Additionally, a competing analysis of light charge particle emission is done where the cumulative contribution of α-emission towards the decay channel is depicted in contrast to the contribution from other light particles (n, 2n,3n) or light charged particles ( 3 H) for both the decaying systems 144 Nd* and 148 Sm*.
