Differential cross-section measurement for 10B(p, αγ1)7Be, 10B(p, p’γ1)10B and 11B(p, p’γ1) 11B reactions
Differential cross-sections of the 10B(p, αγ1)7Be (Eγ = 429 keV), 10B(p, p’γ1)10B (Eγ = 718 keV) and 11B(p, p’γ1) 11B (Eγ = 2124 keV) reactions have been measured at proton laboratory energies of 912–2776 keV at 90°. The proton beam impinged on a thin natB2O3 film evaporated onto a self-supporting thin carbon layer. The incident energies were increased by 10 (20) keV steps in the resonance (off-resonance) regions. Our data are compared with the existing ones from literature. A benchmark procedure was performed by comparing the calculated thick-target yields from the current differential cross-sections with the existing measured thick target gamma-ray yields. The overall systematic uncertainty of the cross-sections was estimated to be about 10 %, mainly related to the target thickness determination.
期刊介绍：
Section B of Nuclear Instruments and Methods in Physics Research covers all aspects of the interaction of energetic beams with atoms, molecules and aggregate forms of matter. This includes ion beam analysis and ion beam modification of materials as well as basic data of importance for these studies. Topics of general interest include: atomic collisions in solids, particle channelling, all aspects of collision cascades, the modification of materials by energetic beams, ion implantation, irradiation - induced changes in materials, the physics and chemistry of beam interactions and the analysis of materials by all forms of energetic radiation. Modification by ion, laser and electron beams for the study of electronic materials, metals, ceramics, insulators, polymers and other important and new materials systems are included. Related studies, such as the application of ion beam analysis to biological, archaeological and geological samples as well as applications to solve problems in planetary science are also welcome. Energetic beams of interest include atomic and molecular ions, neutrons, positrons and muons, plasmas directed at surfaces, electron and photon beams, including laser treated surfaces and studies of solids by photon radiation from rotating anodes, synchrotrons, etc. In addition, the interaction between various forms of radiation and radiation-induced deposition processes are relevant.
