In nucleus–nucleus collisions, the partial-wave scattering matrix, for the total effective complex potential is calculated, which explains the data of angular distribution of elastic scattering cross-sections. Furthermore the absorption cross-section is obtained from the arbitrarily small intervals which helps to derive the fusion cross-section ( σ fus ) data at different center-of-mass energies ( E c.m. ) by collecting the absorption contributions in the interior region of the effective potential. Here, the potential is taken as energy independent and its weakly absorbing nature supports the resonance states in various partial-wave trajectories. Therefore, the resonances show oscillatory behavior changes with respect to energy D (E c.m. ) = d 2 (E c.m. σ fus ) / d E c.m. 2 , which is the second derivative of the product E c.m. . σ fus with respect to E c.m. . In this paper, we have successfully discussed the elastic scattering and fusion cross-sections simultaneously with the results of D (E c.m. ). [ABSTRACT FROM AUTHOR] |
