Data from a recent Be(He,B measurement are used to rule out a possible solution to the cosmological lithium problem based on conventional nuclear physics.
Schematic illustration of the proposed Be destruction mechanism, BeBBe. The energies are in MeV relative to the ground state of B. Subsequently, Be breaks up into two particles.Reuse & Permissions
Figure 2
Maximal resonant contribution of the 16.8-MeV state in B to the Be reaction rate calculated from Eq. (1) vs temperature. For comparison, the rate calculated using the narrow resonance approximation is also shown.Reuse & Permissions
