“…For the 7 Be, 7 Li + 238 U systems, similar results are observed [44]. In the case of 9 Be + 209 Bi,F exp is also smaller than the UFF [11,43]. However, the reduction ofF exp is less pronounced and the suppression factor oscillates along the data points.…”

“…In Section 4, we present the details of the SP potential and discuss the sensitivity of our results to the choice of its parameters. In Table 2 we give the barrier parameters corresponding to the SP potential for the systems considered in this paper and some other weakly bound systems for which data are available in Li + 209 Bi, 9 Be + 208 Pb), [11,43] ( 9 Be + 209 Bi) and [44] ( 7 Li, 7 Be + 238 U).…”

“…This is even more dramatic for light systems for which the main evaporation channels include charged particles (protons and alphas). Therefore, most of the available data in the literature correspond to total fusion (TF) cross section, although there are reports of some measurements of CF and ICF separately [24,25,26,27,28,29,30]. The measurement of EBU cross sections requires difficult exclusive experiments [31,32,33,34,35,36].…”

“…The fusion of weakly bound nuclei, both stable and radioactive, has been the subject of intense theoretical and experimental activities [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48]. Since the beginning of the 1990's, theorists have been facing conflicting ideas about whether the fusion of such nuclei, of great importance in nuclear astrophysics, is enhanced or hindered at low energies owing to the strong coupling to the break-up channel [...…”

Effect of the breakup on the fusion and elastic scattering of weakly bound projectiles onZn64

We study the behavior of the fusion, break-up, reaction and elastic scattering of different projectiles on 64 Zn, at near and above barrier energies. We present fusion and elastic scattering data with the tightly bound 16 O and the stable weakly bound 6 Li, 7 Li and 9 Be projectiles. The data were analyzed by coupled channel calculations. The total fusion cross sections for these systems are not affected by the break-up process at energies above the barrier. The elastic (non-capture) break-up cross section is important at energies close and above the Coulomb barrier and increases the reaction cross sections. In addition we also show that the break-up process at near and sub-barrier energies is responsible for the vanishing of the usual threshold anomaly of the optical potential and give rise to a new type of anomaly.

“…This has primarily been motivated by the present availability of radioactive ion beams, some of which exhibit unusual features like halo/skin structure and large breakup probabilities. A critical understanding of the fusion mechanism with radioactive ion beams is very significant for the understanding of reactions of astrophysical interest and for the production of new nuclei near the drip lines [11][12][13][14][15][16][17][18][19]. The natural theoretical tool for their description is the coupled-channel method.…”

A semiclassical approach has been used to study the effect of channel coupling on the calculations of the total fusion reaction cross section r fus , and the fusion barrier distribution D fus for the systems 6 He þ 238 U and 8 He þ 197 Au. Since these systems invloves light exotic nuclei, breakup states channel play an important role that should be considered in the calculations. In semiclassical treatment, the relative motion between the projectile and target nuclei is approximated by a classical trajectory while the intrinsic dynamics is handled by time-dependent quantum mechanics. The calculations of the total fusion cross section r fus , and the fusion barrier distribution D fus are compared with the full quantum mechanical calculations using the coupled-channels calculations with all order coupling using the computer code and with the available experimental data.
