“…The present 7 Li( 18 O, 17 N) 8 Be reaction data were taken at the same time as the previously reported 7 Li( 18 O, 18 O) 7 Li elastic scattering data [3] at the Warsaw Heavy Ion Cyclotron Laboratory, which provided the 114-MeV 18 O beam for the experiment. The details of the target, detector, and data accumulation system are given in Ref.…”

“…As can be seen, the resolution is sufficiently good to separate the reaction products of interest. Figure 2 shows a typical residual energy spectrum of 17 N from the 7 Li( 18 O, 17 N) 8 Be reaction after subtraction of a background. To extract the yields, the peaks were fitted by the sum of Gauss symmetric functions…”

“…The error in the absolute cross section is about 15%. The resulting angular distributions of the 7 Li( 18 O, 17 N) 8 Be reaction for ground states of 8 [15]. The parameters of the spin-orbit potential were taken from Ref.…”

“…The present work reports angular distributions for the 7 Li( 18 O, 17 N) 8 Be reaction at the energy E lab ( 18 O) = 114 MeV. This reaction was measured simultaneously with 7 Li + 18 O elastic scattering [3] so that combining the deduced 7 Li + 18 O potential parameters with shell-model spectroscopic amplitudes of nucleons and clusters, previously calculated, in a coupled-reaction-channels (CRC) analysis resulted in a detailed test of our interpretation of the 7 Li( 18 O, 17 N) 8 Be reaction data.…”

A further test of the spectroscopic amplitudes used in this study was carried out by their use in a CRC analysis of previously reported 18 O(d, 3 He) 17 N reaction data taken at E d = 52 MeV [4].…”
