Resolving the 11B(p, \({\alpha_0}\)) Cross Section Discrepancies between 0.5 and 3.5 MeV

The reaction 11B(p, 3\({\alpha}\)) is relevant for fields as diverse as material science, nuclear structure, nuclear astrophysics, and fusion science. However, for the channel proceeding via the ground state of 8Be, the available cross-section data shows large discrepancies of both normalization and...

Description
Summary:The reaction 11B(p, 3\({\alpha}\)) is relevant for fields as diverse as material science, nuclear structure, nuclear astrophysics, and fusion science. However, for the channel proceeding via the ground state of 8Be, the available cross-section data shows large discrepancies of both normalization and energy scale. The present paper reports on a measurement of the 11B(p, \({\alpha_0}\)) cross section using an array of modern large area segmented silicon detectors and low beam current on an enriched thin target with the aim of resolving the discrepancies amongst previous measurements.
