Scattering of $^{15}$N Ions by $^{10, 11}$B Nuclei at the Energy of 43 MeV

Abstract

Angular distributions for 15 N elastically scattered from 10,11 B nuclei were measured at the energy of 43 MeV. The experimental data for the 11 B+ 15 N system showed a remarkable increase in differential cross sections at large angles which cannot be explained within the framework of the optical model. Such behavior of the cross sections can be reproduced only by taking into account the contribution of the α-cluster transfer mechanism. Although the experimental data for 10 B+ 15 N system showed an increase in differential cross sections at backward angles, it can be described by optical model calculations.

Further investigation of 10,11B + 58Ni elastic scattering

“…More recently, many other works have been done to resolve these problems. For example, the same findings were found by bombarding odd mass nuclei targets with medium mass projectiles [8], i.e., the static deformation of the nucleus has a major impact on the reaction mechanism at energies above the Coulomb barrier [9,10].…”

“…We note that the measured cross sections agree with the data in an appropriate range, and these findings lead us to infer that the imaginary potential in the energy range from 23 MeV to 35 MeV appears to be replicated well by our calculations. In comparison, the available values of the measured reaction cross section for 8 B+ 58 Ni at different energies are also introduced in figure 9 along with the optical model and the folded calculations as follows, for…”
