Abstract

The reliable value of the ¹¹B(p,α)αα reaction cross-section is of importance for the proton therapy of cancer, thermonuclear fusion, and nuclear astrophysics. Despite its relevance, the mechanism of the reaction is still an open issue. The goal of the study is to obtain new data on the reaction and to update and clarify the available data in the 0.3–2.15 MeV energy range of the proton beam. The results obtained have shown that the ¹¹B(p,α)αα reaction proceeds via two channels, ¹¹B(p,α₁)⁸Be* and ¹¹B(p,α₀)⁸Be, with unequal cross-sections, which agrees with current conceptions. A thin boron target will be studied later to measure the cross-sections of each channel.
