Description
Experiments looking for near-threshold resonances in weakly bound nuclei provide a direct link between nuclear reactions and nuclear structure, via the interaction of discrete states with the continuum.
These states, located near the particle-decay threshold, accumulate most of the continuum
strength in a single state and couple strongly to the decay-channel, exhausting most of the decay-width and
carrying many of its characteristics. In particular, a near-threshold proton resonance in 11B has long been sought since it would be the intermediate state that may help explain the controversially large β−p+ branching ratio from the 11Be nucleus that has been observed in experimental measurements but is not in full agreement with theoretical calculations.
In this works I will discuss a recent experiment carried out at the John D.
Fox Superconducting Linear Accelerator Laboratory at Florida State University
where the near threshold proton resonance at 11.4 MeV in 11B was observed for the first time,
via the 10Be(d,n)11B reaction. The results and implications of our measurement will also be presented.
