Deuteron stripping reaction on 10B and 11B nuclei

This research project was motivated by the predicted existence of a strong resonance in 11B at 11.425 MeV. The hypothetical existence of this resonance has been considered a solution to the large discrepancy between the measured and calculated branching ratio for the phenomenon of beta-delayed proton emission in the neutron-rich nucleus 11Be. FSU’s John Fox Accelerator Laboratory was used to conduct an experiment to search for the resonance, utilizing a deuteron stripping reaction on 10B and 11B targets. A split-pole spectrograph was used to observe excited states in 10B(d,p)11B and 11B(d,p)12B. A focal plane detector was used to measure the positions of proton ejectiles from the reaction at scattering angles from 10 to 50 degrees at five-degree increments. Through the use of the data analysis framework ROOT and the calibration software SPANC, relevant peaks were identified and paired with previously recorded excited states in 11B and 12B. Angular distributions were constructed for these states. Preliminary results will be presented.
