Abstract
A measurement of low-lying states in B-9 was conducted using the Li-6(Li-6,t)B-9 reaction at a beam energy of 56 MeV. The particles resulting from the decay of B-9 into Be-8 + p were detected with position sensitive detectors, and relative energy spectra were obtained from the data using the technique of resonant particle decay spectroscopy. This technique provided a very low background, and the ability to separate the B-9 states that decay by Be-8 + p from those that decay by Li-5 + alpha. Results show that a significant portion of the measured spectrum below approximate to 1.5 MeV cannot be explained by the known states which suggests that these counts arise from the mirror of the 1.68 MeV 1+/2 state of Be-9. It was also shown that the recently observed 1-/2 state decays via the p + Be-8 channel.
