[Eu/Ba]: Clock and r-process Indicator.

COWLEY C.R. and STENCEL R.E.

Abstract (from CDS):

The europium to barium ratio is both a clock and a measure of galactic chemical evolution of the r- and s-processes. We attribute much of the ratio's vertical scatter to real abundance differences attributable to streams and diffusion into and out of the solar neighborhood.
