A primordial r-process?

Baryon density inhomogeneities in the early universe can give rise to a floor of heavy elements (up to $A\approx 270$) produced in a primordial r-process with fission cycling. A parameter study with variation of the global baryon to photon ratio $η$, and under inclusion of neutron diffusion effects was performed. New results concerning the dependence of the results on nuclear physics parameters are presented.
