摘要：

In a brief review of abundances neutron-capture elements (Z > 30) in metal-poor halo stars, attention is called to their star-to-star scatter, the dominance of r-process synthesis at lowest metallicities, the puzzle of the lighter members of this element group, and the possibility of a better s-/s-process discriminant.
