Description
The interaction of deuteron and proton beams with light nuclei is characterized by a wide variety of reactions of interest for both technical and fundamental applications.
The reaction $^7Li(d,n)α$ is characterized by a high neutron yield and high neutron energy (13.125 MeV), which is relevant for conducting radiation tests of modern materials and equipment.
For the reaction $^{11}B(p, α)αα$, reliable knowledge of the cross section is relevant for proton therapy of cancer, the implementation of the boron-proton fusion reaction in thermonuclear energy and the study of the mechanism of primary nucleosynthesis.
Despite the long-standing interest in these processes, the experimental data on cross-sections vary greatly among different authors, and for a number of reactions, cross-section values are not available in the databases.
At the Institute of Nuclear Physics of the Siberian Branch of the Russian Academy of Sciences, at the VITA accelerator neutron source, the cross-sections of the following reactions were measured experimentally in the energy range of 0.3-2.3 MeV:
- $^6Li(d,α)α$, $^6Li(d,p)^7Li$, $^6Li(d,p)^7Li^*$,$^7Li(d,α)^5He$, $^7Li(d,nα)α$, $^{10}B(d,α_0)^8Be$, $^{10}B(d,α_1)^8Be^*$, $^{10}B(d,p_2)^9Be^*$, $^{11}B(d,α_0)^9Be$, $^{11}B(d,α_2)^9Be^*$
- $^{11}B(p,α)αα$, $^{11}B(p,α_0)^8Be$, $^{11}B(p,α_1)^8Be^{**}$
The study was supported by the Russian Science Foundation grant No. 19-72-30005, https://rscf.ru/project/19-72-30005/.
