Production of Be-9 and heavy elements in the inhomogeneous universe

Abstract

The abundances of Be-9 and CNO elements in the inhomogeneous models of pr imordial nucleosynthesis are calculated using an extended network including elements up to Ne-22 in a multizone scheme. It is shown that the Be-9 abundance is two orders of magnitude smaller than that calculated in a simplified two-zone model. Heavy elements are produced mainly in high-density zones, and the abundances of CNO elements, which are seeds of a cosmic r-process, are fairly small in low-density and neutron-rich zones. 12 refs.
