Global optical model potentials for symmetrical lithium systems: 6Li+6Li, 7Li+7Li at Elab = 5–40 MeV

Elastic scattering and reactions of light exotic beams

“…The principal goal of these measurements was spectroscopy of high-lying cluster states via sequential decay, but some angular distributions were reported, notably for elastic scattering from 6 Li and quasi-elastic scattering from 7 Li (inelastic scattering to the 7 Li 1/2 − state could not be separated). The main result of interest here is that the 6 He + 6,7 Li (quasi) elastic scattering was satisfactorily described by optical model calculations using the global 6 Li parameters of Potthast et al [64,65].…”

“…An optical model analysis extracted a total reaction cross section of 1862 mb. Charged particle-γ -ray coincidence measurements were obtained in the same experiment, indicating a large production cross section for 64 Cu, inconsistent with a fusion-evaporation mechanism. A large neutron transfer cross section was therefore inferred.…”

Reaction mechanism study of 7Li(7Li,6He) reaction at above Coulomb barrier energies

“…There have been several studies aimed at understanding the interactions between lithium nuclei at energies close to and far above the Coulomb barrier [1][2][3][4][5][6]. Reactions between these nuclei are very complex, since a variety of reaction mechanisms are competing.…”

“…Since the outgoing 6 He in this reaction is a loosely bound unstable nucleus, it would be interesting to explore the possibility of producing it through the 7 Li( 7 Li, 6 He) reaction. The large positive Q value (Q = +7.279 MeV) of this reaction can be exploited in separating 6 He from other reaction products and initiating further secondary reactions.…”

“…The large positive Q value (Q = +7.279 MeV) of this reaction can be exploited in separating 6 He from other reaction products and initiating further secondary reactions. A number of experiments have been reported using the low energy 6 He beams [7][8][9][10] in recent times.…”
