“…In recent years, there is a lot of data available for complete fusion (CF) cross-sections with 6,7 Li and 9 Be projectiles on various targets [1][2][3][4][5][6][7][8][9][10][11][12][13]. The measured complete fusion cross-sections are found to be suppressed compared to the Coupled Channel calculations or One Dimensional barrier penetration model calculations at above barrier energies.…”

Abstract. We have included breakup effects explicitly to simultaneously calculate the measured cross-sections of the complete fusion, incomplete fusion, and total fusion for 6,7 Li projectiles on various targets using the Continuum Discretized Coupled Channels method. The breakup absorption cross-sections obtained with different choices of short range imaginary potentials are utilized to evaluate the individual α-capture and d/t-capture cross-sections and compare with the measured data. It is interesting to note, while in case of 7 Li projectile the cross-sections for triton-ICF/triton-capture is far more dominant than α-ICF/α-capture at all energies, similar behavior is not observed in case of 6 Li projectile for the deuteron-ICF/deuteron-capture and α-ICF/α-capture. Both these observations are also corroborated by the experimental data for all the systems studied.

“…For fusion-evaporation reactions induced on heavy targets (e.g. [3,[26][27][28]), where the emission of charged particles is hindered by the presence of a strong Coulomb barrier, complete (CF) and incomplete fusion (ICF) contributions can usually be clearly separated. The main finding for such systems is that CF is suppressed above the barrier by about 30% with respect to the prediction of Single Barrier Penetration calculations or Coupled Channel calculations not including coupling to continuum effects.…”

“…Fusion excitation functions in collisions induced by stable weakly bound nuclei have been measured for several systems in a wide target mass range [e.g. [3,[26][27][28][29][30][31][32]. For fusion-evaporation reactions induced on heavy targets (e.g.…”

The reaction dynamics of collisions involving halo or weakly bound nuclei, at energies around the Coulomb barrier, can be strongly affected by the structure of such nuclei. Very strong entrance channel effects have been observed on various reaction pocess such as, elastic scattering, fusion and direct reactions when comparing collision induced by the 6 He and 11 Be halo nuclei with the ones induced by their cores 4 He and 10 Be. Collisions induced by the stable weakly bound nuclei 6 Li, 7 Li show also some peculiarities in comparison to the ones induced by well bound nuclei; coupling with the break-up channel is in fact very important in reproducing low energy data. In this contribution an overview of our present understanding of the discussed topic will be given along with the discussion of some new preliminary results.

“…Further observations showed breakup triggered by nucleon transfer [12][13][14] also played an important role. More recent observations of suppression of complete fusion (∼ 30%) in reactions of Li was generally associated with their low breakup threshold energies [15][16][17]. Measurements of subbarrier breakup fragments [18,19] indicated a link between suppression of complete fusion and prompt breakup (prior to reaching the fusion barrier), which reduces the flux of projectile nuclei available to participate in fusion.…”

Abstract. Experiments with weakly-bound nuclei have demonstrated that breakup significantly affects the reaction outcomes. Coincidence measurements of breakup fragments at sub-barrier energies, using a position sensitive back-angle detector array covering 117• to 167• , have enabled the complete characterisation of the breakup processes in the reactions of the weakly-bound 6,7 Li with 208 Pb. The timescales of different breakup processes were also extracted from the fragments kinematics, enabling a clear characterization of prompt and delayed breakup. The majority of these prompt breakup events are triggered by n-stripping for 6 Li, and p-pickup for 7 Li. The demonstration that the reaction dynamics and outcomes can be significantly determined not only by the properties of the two colliding nuclei, but by the ground-state and excited state properties of their neighbours, is a key insight for understanding and predicting reactions of weakly-bound nuclei near the limits of nuclear existence.
