B with a Super-Enge Split-Pole Spectrograph (SE-SPS) and the Silicon Array for Branching Ratio Experiments (SABRE)*

We used the single-particle transfer reaction ¹⁰B(³He,α) to investigate the structure of the light, neutron-deficient nucleus ⁹B. Previous studies of ⁹B report discrepant values for the energy, width, and spin-parity of this isotope’s first-excited state, which is thought to be the mirror of the 1.65-MeV 1/2+ state in ⁹Be. Experimental results for this state’s energy range between 0.7-1.8 MeV with widths between 0.3-1.5 MeV. We performed the ¹⁰B(³He,α) reaction at Florida State University with a 7.5-MeV ³He beam incident on an isotopically enriched ¹⁰B target. Alpha particles were momentum-analyzed by the new Super-Enge Split-Pole magnetic spectrograph (SE-SPS) and detected at the focal plane, while the decay particles of ⁹B were detected by the Silicon Array for Branching Ratio Experiments (SABRE) at backward laboratory angles. Preliminary results from this experiment will be presented.
