Abstract

The reaction mechanism for the decay of the hot and rotating compound system \({}^{88}\)Mo\({}^{*}\) formed in \({}^{48}\textrm{Ti}+^{40}\)Ca reaction and the time for the emission of outgoing fragments have been analyzed within the quantum-mechanical fragmentation theory based dynamical cluster-decay model, at three incident energies. The incident energy effects have been analyzed by comparing the decay modes at three incident energies, i.e. we have calculated and compared the (i) mass, charge, and angular momentum distribution of the cross section for light particles and intermediate mass fragments, (ii) angular momentum distribution of the reaction cross section, (iii) probability of compound nucleus and evaporation processes in the reaction, (iv) mass variation of the kinetic energy, velocity, penetration path length and time for the penetration process, and (v) average time for the process of emission of light particles, intermediate mass fragments and fission fragments. The reaction mechanism has been analyzed from the study of the variation of the reaction cross section with angular momentum.
