Comparative decay analysis of ¹⁷⁹Re* and ¹⁸⁹Au* formed in the reactions ²⁰Ne+¹⁵⁹Tb, ¹⁶⁹Tm with E_lab=8 MeV/A

The heavy ion induced reactions lead to the formation of composite systems, which subsequently decay because of high excitation energy and angular momentum. The study of decaying composite system facilitates to explore the number of nuclear characteristics and the reaction dynamics. The medium mass composite systems ¹⁶⁴Yb*, ^{176,182,188,196}Pt* and ^200,202Pb* have been studied successfully within the framework of dynamical cluster decay model (DCM). These studies show the emission of light particles, LP (or evaporation residues, ER), intermediate mass fragments, IMF, heavy mass fragments, HMF and symmetric fragments, SF along with signatures of quasi-fission, qf, process in their decay path. The decay of medium mass composite system ¹⁷⁹Re* has also been studied within DCM. In the present work, we investigate the comparative decay of two medium mass composite systems ¹⁷⁹Re* and ¹⁸⁹Au formed in the reactions with same projectile (²⁰Ne) having same E_lab (or same E/A) on two different targets ¹⁵⁹Tb and ¹⁶⁹Tm, for which the experimental data is available
