“…However, most CDCC calculations have a shortcoming [23,24], as they cannot give the ICF and CF cross sections unambiguously [25]. This shortcoming can be avoided within a new dynamical quantum approach that includes SCF as well as ICF from the bound state(s) of the projectile [26]. In addition, the comparison of experimental fusion cross sections with either the predictions of coupled-channel (CC) calculations without the breakup and transfer channels [12][13][14][15][16][27][28][29][30][31] or the predictions of a single barrier penetration model (SBPM) [9][10][11] shows that CF cross sections are suppressed owing to the breakup at energies above the Coulomb barrier.…”

Complete fusion excitation functions of reactions involving breakup are studied by using the empirical coupled-channel (ECC) model with breakup effects considered. An exponential function with two parameters is adopted to describe the prompt-breakup probability in the ECC model. These two parameters are fixed by fitting the measured prompt-breakup probability or the complete fusion cross sections. The suppression of complete fusion at energies above the Coulomb barrier is studied by comparing the data with the predictions from the ECC model without the breakup channel considered. The results show that the suppression of complete fusion are roughly independent of the target for the reactions involving the same projectile.

In this article, we have investigated collective effects of atomic nuclei in presence of a time-dependent potential in Davydov-Chaban Hamiltonian. Since such potential has an explicit time-dependency, in order to obtain the wave function of considered system, we should face with time-dependent Schrödinger equation. Obtaining the wave function could be possible using Lewis-Riesenfeld dynamical invariant method. Appropriate dynamical invariant has been constructed after determining the wave functions and values, the wave function will obtain.

“…Notwithstanding, some ambiguity still remains as to whether the absorption of a given fragment comes from CF or ICF process. More transparent calculations, within classical [28,29] and quantum mechanical [30] methods, have been proposed to unambiguously separate CF and ICF. For instance, the classical dynamical reaction model described in Refs.…”

A systematic study of total fusion involving the weakly bound nuclei 6,7 Li with several light to heavy mass targets at Coulomb energies is presented. Emphasis is given to the role of resonance states (l = 2, J π = 3 + , 2 + , 1 + of 6 Li and l = 3, J π = 7/2 − , 5/2 − of 7 Li) on the total fusion excitation function. A comparative analysis of the effects of resonant breakup on total fusion is performed for both projectiles, using the Continuum-Discretized Coupled-Channel (CDCC) framework. The calculations demonstrate that (i) resonant breakup couplings play a more important role in total fusion than non-resonant couplings, (ii) resonance states with short half-lives are very important for total fusion, as incident energies decreases towards the Coulomb barrier energy where incomplete fusion dominates, and (iii) resonance states with long half-life act as quasi-bound inelastic states, playing a crucial role in complete fusion.
