Elastic and inelastic scattering of 7Li + 18O versus 7Li+16O

“…Transfers contribute weakly to the elastic scattering channel. The B 1 -parameters (curves B 1 ), obtained from the energy dependence of the potential parameters for the 7 Li + 16 O elastic scattering [7,8], fail to describe the 7 Li + 18 O elastic scattering data. One can see, that the curve B 1 has slope smaller than the slope of Table 3 Parameters of Woods-Saxon potential for 7 Li experimental angular distribution.…”

“…The measured spectrum of 18 O in the region of the elastic events is given in the upper panel. The markers show the peaks corresponding to the ground states of 7 Li, 12 C, 16 O and other heavy elements present in the target. The dashed curve represents the background produced by multiparticle-reactions of the type 7 Li( 18 O, 18 O){αt, n 6 Li, and so on} that occurred.…”

“…To the best of our knowledge, the present data are the first to be reported for the system 7 Li + 18 O. The extracted potentials are then compared to those previously obtained for 7 Li + 16 O [7,8] whose structure and reaction Q-values are quite different from those of the 7 Li + 18 O system. The paper is organized as follows.…”

“…The deformation parameters from Refs. [10,11] were used for 7 Li in the present calculations: δ 2 = 2.0 fm, δ 4 = 1.0 fm. The parameters δ λ for 18 O were obtained by matching the calculated cross-sections to the data.…”

“…In the present work, the scattering of 7 Li + 18 O has been measured and the data are analyzed with both the optical model (OM) and coupled-reaction-channels method (CRC) to extract the interaction potentials and to determine the strength of the inelastic and transfer channels that play a major role in the scattering process. To the best of our knowledge, the present data are the first to be reported for the system 7 Li + 18 O.…”
