Measurement of the 11B(p,α0)8Be and the 11B(p,α1)8Be* reactions cross-sections at the proton energies up to 2.2 MeV

Abstract

The proton boron fusion reaction attracts the attention of scientist since the dawn of nuclear physics for its relevance and potential application in different fields, from aneutronic fusion to astrophysics and hadron therapy. This reaction has been studied since the 1930s, but data from different authors differ. Obtaining the reliable experimental data on fundamental parameters (for example, direct or sequential decay, the cross-section, the energy spectrum of α-particles, the orbital angular momentum of α-particles) is still relevant. Measurements of the reactions cross-sections were carried out at the accelerator-based neutron source VITA at Budker Institute of Nuclear Physics (Novosibirsk, Russia) using an α-spectrometer. The 11B(p, α0)8Be and the 11B(p, α1)8Be* reactions cross-sections at the proton energies up to 2.2 MeV have been measured. The obtained data are presented in tabular form.
