Signatures of inhomogeneity in the early universe

The production of elemental CNO in inhomogeneous nucleosynthesis is systematically studied for a much larger region of parameter space than ever before. The Li-7(n, gamma)Li-8(alpha, n)B-11 channel is shown to be the dominant path to CNO production in regions of parameter space in which there is significant CNO production. It is shown that this finding is a clear signal of an inhomogeneous Omega(b) = about 1 universe.
