One- and two-step mechanisms of the ⁹Be(¹²C,¹¹B)¹⁰B reaction at E_lab(¹²C)=65 MeV and the energy dependence of ^11,10B+¹⁰B interactions

Abstract

Angular distributions of the ⁹Be(¹²C,¹¹B)¹⁰B reaction were measured at the energy of E_lab(¹²C)=65 MeV for transitions to the ground and 0.72 MeV (1⁺), 1.74 MeV (0⁺, T=1), 3.59 MeV (2⁺) excited states of the ¹⁰B nucleus and 2.12 MeV (1/2⁻)+2.15 MeV (1⁺) excited states of ¹¹B and ¹⁰B nuclei, respectively. Data were analyzed within the coupled reaction channel (CRC) model including one- and two-step transfer mechanisms. The elastic and inelastic scattering and p-, d-, (d + n)-, (n + p)-, (³He + p)- and (³He + d)-transfer mechanisms were included in the coupled channel scheme. It was found that two-step processes are important for all transitions. Data of ¹⁰B+¹⁰B elastic scattering from the literature were included in the analysis of the energy dependence of optical model parameters for ¹⁰B+¹⁰B and ¹⁰B+¹¹B interactions. A good description of all sets of experimental data was achieved.
