INFLUENCE OF BREAKUP PROCESS IN THE FUSION REACTIONS WITH WEAKLY BOUND NUCLEUS ⁹Be

Abstract

Recent experimental results for the fusion of the weakly bound nucleus 9 Be with spherical targets are analyzed by dynamical classical trajectories approach. In this approach, the Proximity model has been used to calculate the nuclear part of interaction potentials. Having determined the breakup functions and interaction potentials for 9 Be + 124 Sn , 89 Y , 144 Sm and 208 Pb reactions, the complete and incomplete fusion (ICF) cross-sections are calculated by classical trajectories model and our results show a good description of the experimental data. We have stressed on the ICF probability ( P ICF ) for chosen reactions. The obtained results show that the ( P ICF ) based on our calculations are in a good agreement with both experimental data and empirical predictions [J. Hinde et al., Phys. Rev. Lett.89, 272701 (2002)].

No-capture breakup and incomplete fusion reactions induced by stable weakly bound nucleus 9Be

“…[1][2][3][4][5][6][7][8][9][10] The reactions with exotic nuclei observed in the astrophysical processes are of particular importance in the nuclear physics research. Often these nuclei have such low binding energies and few-body cluster structures that they can easily be separated into two or more fragments in the reactions with other nuclei.…”

Unambiguous separation of low-energy fusion processes of weakly bound nuclei

“…In this different context, some of those models (e.g., [49,50]) use concepts and techniques (e.g., classical trajectory, Monte Carlo sampling) that overlap with some involved in the present model. The model has been successfully applied in interpreting fusion measurements of weakly bound nuclei [5,17,51], particle-γ coincidence experiments [19] and isomer ratio measurements [52]. The model is also very useful for optimizing the position of particle detectors, e.g., in breakup measurements [5][6][7] and in experiments that exploit the ICF reaction mechanism [46-48, 53, 54].…”
