“…In addition, reaction cross sections were also derived for some energies using the present data and previously measured data which include those obtained at energies above the barrier for the reaction 7 Li+ 64 Zn. For the 16 O+ 64 Zn system, we were able to derive reaction cross sections in a wide energy range (40-68.5 MeV) using elastic scattering data previously reported.…”

“…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 [10,11,12,13,14,15,16,17,18,19,20,21,22]. The reason for such divergent conclusions has been the lack of a trust-worthy continuum-coupled channels theory.…”

“…Up to now, there is no such a complete theoretical study in this field. Different approaches have been used, such as coupled channel calculations (CCC) that do not take into account the break-up process [19], continuum discrete coupled channel calculations (CDCC) [20,21,22], semi-classical trajectories, survival probability concept and dynamic polarization potentials [10,11,12,13,14,15,16,17,18].…”

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

et al. 2005

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.

In this review we discuss the current status of research in nuclear physics which is being carried out in different centers in the World. For this purpose we supply a short account of the development in the area which evolved over the last 9 decades, since the discovery of the neutron. The evolution of the physics of the atomic nucleus went through many stages as more data become available. We briefly discuss models introduced to discern the physics behind the experimental discoveries, such as the shell model, the collective model, the statistical model, the interacting boson model, etc., some of these models may be seemingly in conflict with each other, but this was shown to be only apparent.The richness of the ideas and abundance of theoretical models attests to the important fact that the nucleus is a really singular system in the sense that it evolves from two-body bound states such as the deuteron, to few-body bound states, such as 4 He, 7 Li, 9 Be etc. and up the ladder to heavier bound nuclei containing up to more than 200 nucleons. Clearly statistical mechanics, usually employed in systems with very large number of particles, would seemingly not work for such finite systems as the nuclei, neither do other theories which are applicable to condensed matter. The richness of nuclear physics stems from these restrictions. New theories and models are presently being developed. Theories of the structure and reactions of neutron-rich and proton-rich nuclei, called exotic nuclei, halo nuclei, or Borromean nuclei, deal with the wealth of experimental data that became available in the last 35 years. Further, nuclear astrophysics and stellar and Big Bang nucleosynthesis have become a more mature subject. Due to limited space, this review only covers a few selected topics, mainly those with which the authors have worked on. Our aimed potential readers of this review are nuclear physicists and physicists in other areas, as well as graduate students interested in pursuing a career in nuclear physics.

The total fusion cross sections for the fusion of weakly bound 9 Be on 27 Al and 64 Zn targets at near and above the barrier have been calculated using one dimensional barrier penetration model, taking scattering potential as the sum of Coulomb and proximity potential and the calculated values are compared with experimental data. For the purpose of comparison of the fusion of weakly bound projectiles and strongly bound projectiles, the total fusion cross sections for the reaction of tightly bound nucleus 16 O on 64 Zn have also been computed using a similar procedure. The calculated values of total fusion cross sections in all cases are compared with coupled channel calculations using the code CCFULL. The computed cross sections using Coulomb and proximity potential explain the fusion reactions well in both cases of weakly bound and strongly bound projectiles. Reduced reaction cross sections for the systems 9 Be+ 27 Al, 9 Be+ 64 Zn and 16 O+ 64 Zn have also been described.
