The optical potential for 6Li-6Li elastic scattering at 156 MeV

Nuclear rainbow scattering and nucleus–nucleus potential

“…We finally note that the rainbow pattern has also been observed in the elastic scattering of 6,7 Li at energies up to around 50 MeV/nucleon [45,46,47] and 9 Be at 18 MeV/nucleon [48]. For example, the elastic 6 Li scattering on the light targets has shown a broad exponential falloff in the cross section at large angles which was identified as the "shoulder" of the primary rainbow maximum.…”

Single nucleon transfer reactions in6Li+6Li collisions at 156 MeV

“…At all emission angles a clear 6Li-7Li-7Be separation was achieved over the full energy range. Some further details of the experimental set up and of the procedures are given elsewhere [7,4,6]. The uncertainty of the absolute scale is estimated to be approximately 10%, mainly arising from uncertainties in the target thickness and beam current integration.…”

“…The experiments studying single nucleon transfer reactions by bombarding 6Li by 6Li ions, have been performed at the Karlsruhe Isochronous Cyclotron, in the context of measurements of the differential cross sections of 6Li + 6Li elastic and inelastic scattering [4,6]. The 156 MeV 6Li beam has been focussed onto a about 3 mg/cm 2 metallic 6Li target (isotopic enrichment>99%) and the energy spectra of the [9] charged ejectiles have been measured by a AE--E surface barrier detector telescope, mounted on a movable arm in a 130 cm #25 scattering chamber.…”

“…By such effects, some information about optical potentials of unstable systems, otherwise hard to explore, seems to be accessible. The case of single nucleon transfer processes in 6Li + 6Li collisions enables studies of two of such systems: 7Li+ 5Li and 7Be § 5He, with an identical entrance channel, for which the optical potential has been recently extensively investigated at ELi = 156 MeV [4]. At that relatively high projectile energy the parameters of the optical potential are fairly welt determined so that some problems from the wellknown ambiguities at lower energies appear to be removed;…”

“…Such data could provide a stronger test of the validity of any model for heavy ion potentials [7,8]. The 6 Li elastic scattering from various targets has been extensively studied with bombarding energies below 200 MeV [7,[9][10][11][12][13][14] [18] was reported in 2000 investigating the coupling-effect between the elastic and the breakup channels at intermediate energy.…”
