“…[20]. Since the Sommerfeld parameter (η ∼ 6) is sufficient large and the relative energies of the breakup fragments are not too high, we can assume that the projectile, as well as the breakup fragments, follow a Coulomb trajectory.…”

α-d coincidence data were studied for the 6 Li + 59 Co reaction at E lab = 29.6 MeV. By using a kinematic analysis, it was possible to identify which process, leading to the same final state, has the major contribution for each of the selected angular regions. Contributions of the 6 Li sequential and direct breakup to the incomplete fusion/transfer process were discussed by considering the lifetimes obtained by using a semiclassical approach, for both breakup components.

“…The 6 Li nucleus exhibits a pronounced cluster structure with a very low binding energy in the α− d channel of 1.47 MeV, therefore it is expected to break up very easily. Many exclusive breakup studies exist in the literature, mainly at near-barrier energies, on light [59,60], medium [61][62][63][64][65], and heavy targets [66][67][68][69][70][71]. Coupling effects on the elastic scattering have been also studied [72][73][74].…”

Global descriptions and decay rates for continuum excitation of weakly bound nuclei

In this work we will present an overview of our global studies on continuum excitations induced by protons, for the weakly bound nuclei 6 Li, 7 Li and 9 Be, presenting strong clustering modes. Measurements are made in inverse kinematics and extensive simulations have been developed, to corroborate the analysis and interpretation of the results. The focus of the measurements is on the breakup reaction, but simultaneously this research is complemented by the study of all involved reaction channels, including elastic scattering. In this respect our theoretical interpretation in a Continuum Discretized Coupled Channel approach can be fully validated. Between our sound conclusions we can underline the following: the non reciprocity between the strengths of the breakup probability and the coupling to continuum; the experimental validation of a continuum discretization for three body Continuum Discretized Coupled Channel theories; and last but not least the unique possibility for deducing continuum decay rates of borromean nuclei in proton induced studies, by considering the kinematics of the target recoil. Other specific conclusions for each system will be discussed.

“…In order to gain insight into the dynamics of the SBU and DBU processes, we use a semiclassical approximation, following the procedure previously adopted in [33]. This hypothesis is valid as long as the Sommerfeld parameter η is large (η ∼ 6).…”

Projectile breakup dynamics for 6Li + 59Co : Kinematical analysis of $ \alpha$ - d coincidences

et al. 2010

A study of the kinematics of the α-d coincidences in the 6 Li + 59 Co system at a bombarding energy of E lab = 29.6 MeV is presented. With exclusive measurements performed over different angular intervals it is possible to identify the respective contributions of the sequential and direct projectile breakup components. The angular distributions of both breakup components are fairly well described by the Continuum-Discretized Coupled-Channels framework (CDCC). Furthermore, a careful analysis of these processes using a semiclassical approach provides information on both their lifetime and their distance of occurrence with respect to the target. Breakup to the low-lying (near-threshold) continuum is delayed, and happens at large internuclear distances. This suggests that the influence of the projectile breakup on the complete fusion process can be related essentially to direct breakup to the 6 Li high-lying continuum spectrum.PACS. 25.70.Mn Projectile and target fragmentation
