Effect of the exit reaction channels onLi6+O18elastic scattering

“…For systems where the projectile and target differ by a single nucleon, a 3He or even an alpha particle, the increased cross sections have been shown to arise from elastic transfer of single nucleons or clusters between the projectile and target during the scattering process. A recent measurement of 6Li + l80 elastic scattering [1,2], however, showed an enhanced large angle cross section where elastic transfer would be expected to be small, since it would involve transfer of a l2B cluster. Previous experiments [3] have shown that this possibility is unlikely due to the small overlap of l80 with a l2B + 6Li cluster.…”

“…1 ot Ref. [1]) the most pronounced was the lx0 (6Li,7Li)l70 one-neutron pickup leading to different states in l70 [2], PHYSICAL REVIEW C 91, 044612 (2015) The first ingredients needed to understand the influence of coupling to these neutron transfer reactions on the elastic scattering through the CRC method are the distorting potentials for the various channels. The CDCC calculations described in the previous section have shown that breakup couplings do not contribute to the observed backward-angle rise in the elastic scattering angular distribution.…”

“…In the exit channel, two OM potentials were tried -that from the global prescription of Cook [13] and that proposed by Rudchik et al (Table 2 of Ref. [2]). …”

“…References [1,2] report detailed angular distributions for scattering and reactions produced by bombarding a hLi target with a 114 MeV ,sO beam and then detecting both the heavy and light particle reaction products at forward angles, thus yielding a data set with both forward-and backward-angle scattering and reaction products. The experimental data for 'Corresponding author: keeley@fuw.edu.pl both the scattering and reactions were analyzed in Refs.…”

“…The experimental data for 'Corresponding author: keeley@fuw.edu.pl both the scattering and reactions were analyzed in Refs. [1,2] with direct reaction models that did not isolate the results of couplings to the breakup channels or the influence of single-nucleon transfer on the large angle cross sections. Moreover, the optical model (OM) potentials needed for the reaction calculations were fitted to the data, which may obscure important underlying strong coupling effects.…”
