Near-Threshold Resonance Helps Explain a Controversial Measurement of Exotic Decay in Beryllium-11

Caption

The emission of a proton from the exotic neutron-halo nucleus beryllium-11. A narrow resonance in boron-11 suggests its proton emission is a two-step process (red arrows), not an exotic process (black arrow). The inset shows the resonance’s location.
