“…Especially, the processes induced by 6 Li and 7 Li nuclei gained attention due to the break-up effect of 6 Li into d + α, and 7 Li into t + α which plays a crucial role in the elastic scattering of 6 Li and 7 Li, for a range of target nuclei at different energies. There are extensive experimental measurements and theoretical studies for 6 Li + 28 Si nuclear system, and the available data are classified into two categories: experimental data near the Coulomb barrier energy EC [1][2][3][4][5][6][7] and the data above EC [8][9][10][11][12][13][14]. It is appropriate here to disregard particular effects due to coupling to other reaction channels when studying the elastic scattering mechanisms between two ions at energies well above the EC.…”

“…That is, direct reactions dominate over fusion ones, particularly as the energy approaches the barrier energy V B . As claimed by Pakou et al [4][5][6][7][8], direct reactions are not just breakup processes, but also transfer channels, which may even be more important than breakup at some energies for these systems.…”

“…This new phenomenon has been termed the breakup threshold anomaly (BTA) [3]. Based on their measured transfer cross section much higher than the breakup cross section at the near barrier energy for the 6,7 Li + 28 Si system, Pakou et al [4][5][6][7][8] argue that transfer channels can also be important at low energies for some weakly bound systems, and therefore those channels may be the main reason for the nondecreasing of the imaginary potential at near barrier energies. The BTA has been investigated in a large number of nuclear systems involving weakly bound projectiles with a variety of medium and large mass targets, for instance 9 Be with 27 Al [9], with 64 Zn [10][11][12][13], with 144 Sm [14,15] and with 208 Pb, 209 Bi [16,17]; 6 Li and 7 Li with targets 208 Pb [3,18], 27 Al [19][20][21], 144 Sm [22], 58,64 Ni [23,24], 59 Co [25], 90 Zr [26], 138 Ba [11,27,28], 28 Si [6].…”
