Query: 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 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.
