“…In present study, one dimensional penetration model [21,22] is used to study the fusion cross section, σ f us . In this formalism, the σ f us defines as the summation on the quantummechanical transmission probability through the potential barrier for a specified angular momentum l and center-of-mass energy, namely T l (E c.m.…”

The behaviors of barrier characteristics and fusion cross sections are analyzed by changing neutron over wide range of colliding systems. For this purpose, we have extended our previous study (Eur. Phys. J. A 48, 21 (2012), it is devoted to the colliding systems with neutron-rich nuclei) to 125 isotopic systems with condition of 0.5 ≤ N/Z ≤ 1.6 for their compound nuclei. The AW 95, Bass 80, Denisov DP and Prox. 2010 potentials are used to calculate the nuclear part of interacting potential. The obtained results show that the trend of barrier heights V B and positions R B as well as nuclear V N and Coulomb V C potentials (at R = R B ) as a function of (N/Z − 1) quantity are non-linear (second-order) whereas the fusion cross sections follow a linear-dependence. 25.60.Pj, 25.70.Jj

“…The characteristics of these nuclei could enhance the cross section for selected direct channels (for example, breakup or neutron transfer). At energies around the potential barrier, where the terms connecting the different exit channels of the scattering are no longer negligible with respect to the kinetic energy of the particles, coupling effects become important modifying the probability for elastic scattering [78] and fusion [79,80]. The latter process in particular was the centre of much interest shortly after the discovery of halo nuclei, as it was speculated that the large spatial extension of neutron matter could lead to a large enhancement of the fusion probability.…”

Abstract.The first beam of post-accelerated radioactive ions was realized in 1989 at the Louvainla-Neuve research facility. The method employed two coupled cyclotrons to produce, separate and re-accelerate the species of interest. Several technological challenges were solved in the process, to obtain pure and intense beams for use in nuclear physics research. Similarly, new techniques were developed and refined for the measurement of the nuclear reactions induced by the radioactive beams. The available energy range made the facility particularly suited for nuclear astrophysics studies, and important results were obtained in the determination of stellar reaction rates using beams of 7 Be, 13 N, 18 F, 18,19 Ne. A beam of 6 He ions was extensively used in studies of the nuclear structure (halos, molecular states) and dynamics (the reaction process at energies around the potential barrier).

“…In heavy ion reactions, coupling to different channels affects the fusion process and gives information about the nuclear properties through the fusion excitation function [1] and the barrier distribution (BD) [2]. Sometimes, even though a coupling appears to describe the excitation function quite well, it may fail to explain the BD.…”
