${}^6\mathrm{He}+{}^{120}\mathrm{Sn}$ elastic angular distributions. The experimental data of this experiment (solid circles) are compared with OM (dashed lines), three-body CDCC (dotted lines), and four-body CDCC (solid lines) calculations. See text for details.Reuse & Permissions

Figure 4

Reduced reaction cross section versus reduced energy for the ${}^6\mathrm{He}+{}^{120}\mathrm{S}$ reaction compared to other systems of similar masses: (a) from Refs. [26, 27] and (b) from Ref. [28]. The dashed lines are to guide the eyes. The total reaction cross sections were obtained from optical model fits of the experimental angular distributions. For the ${}^6\mathrm{He}+{}^{120}\mathrm{Sn}$ system, we plot the average values of OM and four-body CDCC calculations from Table . The upper and lower parts of Fig. 4 report the same data reduced by two different methods (see text for details).Reuse & Permissions
