Abstract

We investigate the nucleosynthesis that includes the production of heavy elements be- yond 7Li in the inhomogeneous big-bang nucleosynthesis. We can get the parameter regions from light elements of 4He and D for the baryon-to-photon ratio obtained by CMB. In these allowed pa- rameter region, we have confirmed that the heavy elements beyond Fe can be produced appreciably, where p- and/or r-elements are produced well compared to the solar system abundances.
