The fusion cross-section of Li-9 + Zn-70 system is analyzed for different cluster models and various density distributions of the 9 Li nucleus by using the optical model at energies near and below Coulomb barrier. To make a comprehensive analysis and show the effect of neutron rich 9 Li nucleus, our study consists of two parts. First, we obtain five different density distribution of the 9 Li nucleus. As a second part, we evaluate some cluster models of Li-9 which consist of He-4 + H-3 + n + n, He-6 + H-3 , (7) Li + n + n and Li-8 + n. The microscopic nucleon-nucleon double folding potential for real and imaginary parts is applied. It is seen that the results obtained with this study are in better agreement with the experimental data than previous works, especially at low energies. Finally, we acquire the RB and VB parameters for all the densities and cluster cases of the (9) Li +( 70) Zn fusion reaction. (C) 2022 Elsevier B.V. All rights reserved. |
