“…In the case of the 10 B projectile, the elastic-scattering angular distributions and total reaction cross-sections are predicted using the global OMPs of 9 Be and 7 Li. Figures 6 and 7 present the comparisons of elasticscattering angular distributions between theoretical predictions and experimental data [18] for 27 Al and 28,30 Si targets at the bombarding energies from 33.7 MeV to 50 MeV. Figure 6 shows slight oscillations in the angular distributions appearing in the angular range from 50° to 80°, while agreement between the predictions of 9 Be global OMP and experimental data is rather good.…”

We achieved a set of 9Be global phenomenological optical model potentials by fitting a large experimental dataset of the elastic scattering observable for target mass numbers from 24 to 209. The obtained 9Be global optical model potential was applied to predict elastic-scattering angular distributions and total reaction cross-sections of 8,10,11B projectiles. The predictions are made by performing a detailed analysis comparing with the available experimental data. Furthermore, these elastic scattering observables are also predicted for some lighter targets outside of the given mass number range, and reasonable results are obtained. Possible physical explanations for the observed differences are also discussed.

It was first noted during the 1970s that finite-range distorted wave Born approximation (FR-DWBA) calculations were unable satisfactorily to describe the shape of the angular distributions of many single-proton (and some single-neutron) transfer reactions induced by heavy ions, with calculations shifted to larger angles by up to ∼ 4 • compared with the data. These reactions exhibited a significant mismatch, either of the reaction Q value or the grazing angular momentum of the entrance and exit channels, and it was speculated that the inclusion of multi-step transfer paths via excited state(s) of the projectile and/or ejectile could compensate for the effect of this mismatch and yield good descriptions of the data by shifting the calculated peaks to smaller angles. However, to date this has not been explicitly demonstrated for many reactions. In this work we show that inclusion of the two-step transfer path via the 4.44-MeV 2 + excited state of the 12 C projectile in coupled channel Born approximation calculations enables a good description of the 208 Pb( 12 C, 11 B) 209 Bi single-proton stripping data at four incident energies which could not be described by the FR-DWBA. We also show that inclusion of a similar reaction path for the 208 Pb( 12 C, 13 C) 207 Pb single-neutron pickup reaction has a relatively minor influence, slightly improving the already good description obtained with the FR-DWBA.

“…In the analysis for this system the values of radius parameters for real and imaginary parts were kept fixed at 1.06 fm for all the calculations. A similar fitting procedure can also be found in the literature [2,7] for 11 B + 209 Bi system. The corresponding values of the energy dependence of the real and imaginary potentials for the 11 B + 232 Th system are shown in Fig.…”

“…One of the manifestations of this feature is a strong energy dependence of the optical model potential deduced from analyses of elastic scattering angular distributions at energies around the Coulomb barrier [1,2]. The study of elastic scattering angular distributions determine parameters of the real and imaginary parts of the nuclear interaction potential.…”

Abstract. The elastic scattering cross sections of 11 B projectile on the 232 Th target have been measured at different bombarding energies close to the Coulomb barrier. The data has been analyzed for this system using the optical model ECIS code with phenomenological Woods-Saxon forms of the optical potentials. The energy dependence of the volume type real and imaginary parts of the optical potentials are derived from the best fit of the experimental angular distribution data. The total reaction cross sections are obtained from optical model analysis.
