Primordial Heavy Element Production

subject

description

A number of possible mechanisms have been suggested to generate density in-homogeneities in the early Universe which could survive until the onset of primordial nucleosynthesis (Malaney and Mathews 1993). In this work we are not concerned with how the inhomogeneities were generated but we want to focus on the effect of such inhomogeneities on primordial nucleosynthesis. One of the proposed signatures of inhomogeneity, the synthesis of very heavy elements by neutron capture, was analyzed for varying baryon to photon ratios n and length scales L. A detailed discussion is published in (Rauscher et al. 1994b). Preliminary results can be found in (Thielemann et al. 1991; Rauscher et al. 1994a).
