A Study of the Low-Lying States of <sup>9</sup>B with a 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 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.
