A theoretical study on the impact of centrifugal potential and fragment identification in the decay of compound nuclei (A(CN)=60 & 100)

Decay analysis of compound nuclei such as Zr-96* and Ru-98+ formed in Ca-48 + Ca-48 and S-34+Ni-64 reactions, respectively, is studied using two theoretical frameworks, dynamical cluster-decay model (DCM) and PACE4. To explore the decay dynamics in a relatively lighter mass region (A(CN) approximate to 60), two more reactions are picked (i) S-34 + Mg-26 forming the "Ni* compound nucleus, (ii) another one involving the odd mass projectile, Cl-35 + Al-27 -> Zn-62*. In DCM, the fusion excitation functions are calculated using sticking (Is) and nonsticking (I-NS) limits of the moment of inertia. For the chosen reactions, fusion cross-sections are equivalent to evaporation residue (ER) cross-sections (sigma(fus) = sigma(ER)) as fission cross-sections are negligible. A lower magnitude of maximum angular momentum (l(max)) is obtained via the I-NS approach in comparison to the I-NS approach and the angular momentum obtained via the I(NS )approach is closer to the experimental observations. The structure and magnitude of fragmentation potential and preformation probability (P-0) depend on the choice of moment of inertia and the magnitude of angular momentum involved. Besides this, PACE4 is employed to address the fusion cross-section of chosen reactions. The most probable decay channel is identified using both DCM and PACE4 approaches.
