“…A large enhancement of sub-barrier fusion cross sections have been experimentally observed in many reaction systems with positive Q-value neutron transfer channels [84][85][86][87][88][89][90]. Many efforts have been made to study the effect of the neutron transfer [84,[91][92][93][94][95][96][97][98][99][100][101].…”

We perform a systematic study of capture excitation functions by using an empirical coupled-channel model. In this model, a barrier distribution is used to take effectively into account the effects of couplings between the relative motion and intrinsic degrees of freedom. The shape of the barrier distribution is of an asymmetric Gaussian form. The effect of neutron transfer channels is also included in the barrier distribution. Based on the interaction potential between the projectile and the target, empirical formulas are proposed to determine the parameters of the barrier distribution.Theoretical estimates for barrier distributions and calculated capture cross sections together with experimental cross sections of 220 reaction systems with 182 Z P Z T 1640 are tabulated. The results show that our empirical formulas work quite well in the energy region around the Coulomb barrier. This model can provide prediction of capture cross sections for the synthesis of superheavy nuclei as well as valuable information on capture and fusion dynamics.

The use of radioactive beams opens a new frontier for fusion studies. The coupling to the continuum can be explored with very loosely bound nuclei. Experiments were performed with beams of nuclei at or near the proton and neutron drip-lines to measure fusion and associated reactions in the vicinity of the Coulomb barrier. In addition, the fusion yield is predicted to be enhanced in reactions involving very neutron-rich unstable nuclei. Experimental measurements were carried out to investigate if it is feasible to use such beams to produce new heavy elements. The current status of these experimental activities is given in this review.

“…In view of the experimental benefits of D qel over D f us , the function D qel may be considered to be a suitable alternative to D f us . Barrier distributions derived from the above two complementary approaches have been found to be similar for the systems where both the reactants are strongly bound [2,4,5]. In the past two decades, the influence of breakup of weakly bound projectiles, like 6,7 Li and 9 Be on fusion cross sections has been widely studied [6][7][8][9].…”

Study of Quasielastic scattering for ⁷Li+¹⁵⁹Tb at around- barrier energies

Abstract. Quasielastic scattering cross sections for the reaction 7 Li+ 159 Tb have been measured at large backangles, at energies around the Coulomb barrier. The quasielastic barrier distribution has been extracted from the measured quasielastic scattering excitation function, including and excluding α particle contribution. The peak of the quasielastic barrier distribution including α particle contribution shows a shift towards higher energy compared to the peak of the distribution without α particles. The quasielastic barrier distribution when compared to the calculated fusion barrier distribution, appears to show reasonable agreement for the system.
