“…Such distributions, as shown in Ref. [8], may bring forth the "coupling of the collective degrees of freedom" and, consequently, the enhancement of the interaction cross section, in particular, in the sub-barrier energy region.…”

Abstract. Excitation functions of the reaction products were measured for the reactions induced by 4,6 He projectiles on 208,206 Pb targets, leading to the same compound nucleus. The excitation functions for the 2n evaporation channels were obtained at energies below the sub-Coulomb barrier region. A large value of the fusion cross section was observed in the case of the reaction induced by the weakly bound 6 He projectile. This reflects an unusual mechanism is present in reactions induced by weakly bound nuclei.

“…As suggested in [7], the neutron transfer channels could have an important role in nuclear fusion due to the fact that neutrons are insensitive to the Coulomb field and their transfer might start at larger separations than for other particles. This interaction, at separations larger than the sum of nuclei radii, could therefore have an influence on how fusion proceeds.…”

This paper presents values of complete fusion cross sections deduced from activation measurements for the reactions 6 Li + 120 Sn and 7 Li + 119 Sn, and for a projectile energy range from 17.5 to 28 MeV in the center-of-mass system. A new deconvolution analysis technique is used to link the basic activation data to the actual fusion excitation function. The complete fusion cross sections above the barrier are suppressed by about 70% and 85% with respect to the universal fusion function, used as a standard reference, in the 6 Li and 7 Li induced reactions, respectively. From a comparison of the excitation functions of the two systems at energies below the barrier, no significant differences can be observed, despite the two systems have different n-transfer Q values. This observation is supported by the results of coupled reaction channels (CRC) calculations.

“…[3]. The importance of neutron transfer with positive Q-values on nuclear fusion (capture) originates from the fact that neutrons are insensitive to the Coulomb barrier and therefore they can start being transferred at larger separations before the projectile is captured by target-nucleus [4]. Therefore, it is generally thought that the sub-barrier fusion cross section will increase [5][6][7] because of the neutron transfer.…”

Abstract. The roles of nuclear deformation and neutron transfer in sub-barrier capture process are studied within the quantum diffusion approach. The change of the deformations of colliding nuclei with neutron exchange can crucially influence the sub-barrier fusion. The sub-barrier capture reactions following the neutron pair transfer are used for the indirect study of neutron-neutron correlation in the surface region of nucleus. The strong surface enhancement of the neutron pairing in nuclei 48 Ca, 64 Ni, and 116,124,132 Sn is demonstrated. Comparing the capture cross sections calculated without the breakup effect and experimental complete fusion cross sections, the breakup was analyzed in reactions with weakly bound projectiles 6,7,9 Li and 9 Be. A trend of a systematic behavior for the complete fusion suppression as a function of the target charge and bombarding energy is not achieved.
