Abstract

The difficulty in investigating fusion processes using neutron-rich halo nuclei resides in comprehending the system that allows the coupling between the elastic and breakup channels. The main objective of the present calculations is to identify the ideal coupling coefficient. that takes into account the effects of channel-coupling in computing the overall cross section of fusion section σ_fus, the distribution barrier of the fusion D_fus, and the probability P_fus for the subsequent systems ⁸He + ¹⁹⁷Au,⁶He + ¹⁹⁷Au, and ¹¹Li + ²⁰⁸Pb, utilizing a quantum mechanical methodology. The coupled-channel (CC) code is used for doing quantum computations that include coupled channels. The quantum mechanical technique accurately agrees with the current observable data. Theoretical predictions of quantum mechanics exhibit exceptional agreement with the corresponding experimental results, especially in the area under the barrier of Coulomb.
