A Study of the ½<sup>+</sup> State of <sup>9</sup>B with the Super-Enge Split-Pole Spectrograph (SE-SPS) and the Silicon Array for Branching Ratio Experiments (SABRE)
ORAL
Abstract
We used the single-particle transfer reaction 10B(3He,α) to investigate the low-lying structure of the light, neutron-deficient nucleus 9B. Previous studies of 9B report discrepant values for the energy and width of this isotope’s first-excited state, 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 Super-Enge Split-Pole 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.
