Abstract

While 9Be is expected to provide a test of inhomogeneous models of primordial nucleosynthesis, we show that the previous estimate by the simplified two-zone model of neutron diffusion overestimated the 9Be abundance at least two orders of magnitude. The abundances of CNO elements expected to be the seeds of cosmic r-process are very small in the proper range of parameters consistent with the abundances of light elements.
