Measurement of the 10B(d,n)11C reaction cross-section in the energy range of 0.05–0.57 MeV in inverse kinematics

Abstract

The excitation function for the ¹⁰B(d,n)¹¹C reaction was measured in the energy range of 0.05–0.57 MeV. The measurements were performed using the inverse kinematic reaction ²H(¹⁰B,n)¹¹C to reduce the background specific to the experiments with deuteron beams and to prevent the leakage of ¹¹C recoil nuclei from the target. Two scintillation detectors based on NaI(Tl) crystals operating in coincidence mode were used to detect γ-rays with an energy of 0.511 MeV produced during the β⁺ decay of ¹¹C. The cross-section of the ²H(¹⁰B,n)¹¹C reaction was obtained from the analysis of the decay curve of ¹¹C after irradiation taking into account the detection efficiency of the system, the concentration of deuterium atoms in the target and the stopping power for boron ions. Then the cross-section of the ¹⁰B(d,n)¹¹C reaction was calculated using known kinematic equations. The obtained cross-section data are generally in agreement with the data previously reported for deuteron energies less than 0.2 MeV and are inconsistent with the data corresponding to energies greater than 0.5 MeV. The experimental data in the energy range of 0.2–0.5 MeV were obtained for the first time.
