Scientific paper

Shell-model calculations, using both p-shell and spd-shell interactions, have been used to predict the spectroscopic properties of low-lying states in 9Li. From this information, we have obtained new estimates for the rate of the 8Li(n, γ)9Li reaction, which may act to limit the production of heavy elements during an inhomogeneous big bang. The two calculations produce reaction rates which differ by about a factor of 2 at the temperatures of interest, demonstrating the uncertainties in this approach. However, the spd calculation appears to be the more reliable of the two.
