“…This will enable several activation measurements at different energies to be simultaneously undertaken with a fixed beam energy. This has already been done in previous similar experiments [40,42,[44][45][46][47][48][49][50], thus reducing the beam time needed for the measurement. However, using a stack introduces problems which can complicate the interpretation of the activation results.…”

“…For example, enhanced fusion cross sections have been observed for 28 Si + 94 Zr [10], 32 S + 96 Zr, 110 Pd [11,12] and 40 Ca + 48 Ca, 96 Zr, 124,132 Sn [13][14][15][16] systems compared to their isotopic counterparts characterized by lower Q values for neutron transfer. However, the fusion excitation functions for systems like Sn+Ni, Te+Ni [17], O+Ge [18], and Ni+Mo [19] do not show significant differences, when different isotopes of the colliding nuclei are considered, even though the systems present very different Q values for multineutron transfer channels.…”

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.

“…For reactions induced by weakly bound nuclei [16,17,25,26,27,28,39,40,41] and exotic nuclei [18,19,20,21,22,38,42,43,44,45,46], the breakup channel is open and plays a key role in the fusion process near the Coulomb barrier similarly to the transfer-channel coupling described in the previous section. It is therefore appropriate to use the Continuum-Discretized Coupled-Channel (CDCC) approach [47,48,49,50] to describe the influence of the breakup channel in both the elastic scattering and the fusion process at sub-barrier energies.…”

“…Recent studies with Radioactive Ion Beams (RIB) indicate that the halo nature of 6,8 He [18,19,20,21,22], for instance, does not enhance the fusion probability as anticipated. Rather the prominent role of one-and two-neutron transfers in 6,8 He induced fusion reactions was definitively demonstrated.…”

With the recent availability of state-of-the-art heavy-ion stable and radioactive beams, there has been a renew interest in the investigation of nuclear reactions with heavy ions. I first present the role of inelastic and transfer channel couplings in fusion reactions induced by stable heavy ions. Analysis of experimental fusion cross sections by using standard coupled-channel calculations is discussed. The role of multi-neutron transfer is investigated in the fusion process below the Coulomb barrier by analyzing 32 S+ 90,96 Zr as benchmark reactions. The enhancement of fusion cross sections for 32 S+ 96 Zr is well reproduced at sub-barrier energies by NTFus code calculations including the coupling of the neutron-transfer channels following the Zagrebaev semi-classical model. Similar effects for 40 Ca+ 90 Zr and 40 Ca+ 96 Zr fusion excitation functions are found. The breakup coupling in both the elastic scattering and in the fusion process induced by weakly bound stable projectiles is also shown to be crucial. In this lecture, full coupled-channel calculations of the fusion excitation functions are performed by using the breakup coupling for the more neutron-rich reaction and for the more weakly bound projectiles. I clearly demonstrate that Continuum-Discretized Coupled-Channel calculations are capable to reproduce the fusion enhancement from the breakup coupling in 6 Li+ 59 Co.

X‐ray spectrometry: a powerful tool for the measurement of complete fusion of weakly bound nuclei

We describe how the method of detection of delayed K x-rays produced by the electron capture decay of the residual nuclei can be a powerful tool in the investigation of the effect of the breakup process on the complete fusion (CF) cross-section of weakly bound nuclei at energies close to the Coulomb barrier. This is presently one of the most interesting subjects under investigation in the field of low-energy nuclear reactions, and the difficult experimental task of separating CF from the incomplete fusion (ICF) of one of the breakup fragments can be achieved by the x-ray spectrometry method. We present results for the fusion of the 9 Be + 144 Sm system.
