Abstract

Experimental data on the yield of nuclear-reaction products from boron-containing crystalline targets irradiated with a deuterium ion beam with an energy of <50 keV at the HELIS ion accelerator (Lebedev Physical Institute) are presented. Natural boron and boron carbide (B4C) are used as targets. For comparison, experiments on the same setup to measure the yield of nuclear reaction products during the irradiation of boron-containing targets with a neutron flux from a Ti (99.99%) converter target are carried out. Semiconductor detectors, CR-39 track detectors, and neutron scintillation spectrometers are used to record the nuclear-reaction products (charged particles and neutrons). The possibility of initiating nuclear reactions of 10B + n → 7Li + α and p + 11B → 3α with a deuterium ion beam with an energy of <50 keV is demonstrated. However, the high background from the main products of nuclear reactions (D + D) (protons and neutrons) do not allow quantitative estimates of the yield of alpha particles of nuclear-reaction products from proton and neutron capture by boron. The obtained results may be important in the field of radiation medicine for the proton- and neutron-capture therapy of oncological diseases.
