Elastic scattering of Be7+Si28 at near-barrier energies

Abstract

Angular distribution measurements were performed at each energy with the multidetector array EXPADES in conjunction with two Parallel-Plate Avalanche Counters (PPAC) to enable beam ray reconstruction of the events. The data are analyzed in a double-folding framework and the energy evolution of the optical potential as well as the total reaction cross sections are deduced and discussed.

Elastic scattering for the B8 and Be7+Pb208

“…Our conclusions are as follows: 7 Be appears to behave exactly as expected and its (quasi)elastic scattering angular distributions seem well understood in the context of CDCC calculations using a 4 He + 3 He cluster model, in agreement with what was found for the 7 Be + 28 Si [53] and 58 Ni [54] systems. While the predicted suppression of the Coulomb rainbow peak for heavier targets remains to be confirmed experimentally, the good agreement obtained between the CDCC calculations and the measurements for three widely separated targets strongly supports the validity of the model.…”

“…Our study was complemented by the first measurement of the elastic scattering process for the 7 Be + 208 Pb system in the energy range around the Coulomb barrier, which was not only necessary to fix the core-target interaction in a 7 Be + p cluster model of 8 B but also of considerable interest in itself (see Ref. [51]), especially in relation to the similarities of 7 Be with the binding energy of 6 Li and the nuclear structure of 7 Li, as underlined in the recent works by Sgouros and collaborators [52,53]. A quite comprehensive overview of previous experiments aimed at studying the 7 Be-induced reaction dynamics has been already given in Ref.…”

Applicability of 9Be global optical potential to reactions of 7,10,11,12Be *

“…For the radioactive non-halo projectile, the elastic scattering angular distributions are calculated using the global OMP. Figure 1 displays the comparison of theoretical results with the experimental data [7][8][9] for + and + systems. The incident energies of range from 10.0 MeV to 22.0 MeV.…”

“…3. For , the data [8] are derived from the elastic scattering angular distributions at sub-and near-barrier energies. The calculations are in agreement with the data.…”

Inclusive $α$ Production for $^{6}$Li+$^{51}$V System

“…The breakup of weakly bound light nuclei such as 6 Li with cluster structure (α+d) is well established phenomenon while moving in the field of target nucleus [1][2][3][4][5]. Numerous observations assist for larger yield of α-particles in comparison to its complementary constituent and the mechanism lying behind is still the current interest of investigation for projectiles with cluster structures like 6,8 He, 6,7 Li, 7,9 Be [6][7][8][9]. In a representative example P+T → (a+x)+T, when any one or more than one of the outgoing fragments is unrecognized then reaction is inclusive with respect to unobserved particle(s).…”
