Spectroscopy of Resonances in 9B with the FSU-LSU Split-Pole Spectrograph

The cross sections of nuclear reactions between the radioactive isotope 7Be and deuterium, a possible path of reducing the production of mass-7 nuclides in Big-Bang nucleosynthesis, have recently been measured with the ANASEN active-target detector system at the RESOLUT facility of Florida State University [1]. In order to further reduce the uncertainties in the reaction rates of Big-Bang nucleosynthesis, we performed an indirect experiment with the 10B(3He,alpha) reaction with the newly commissioned large-acceptance Enge Split-Pole Spectrograph. The implications for the synthesis of 7Li will be discussed.
