The long-lived cosmochronometer87Rb (T 1/2=4.8×1010 yr) is studied. As its origin is partly due tos- and partly tor-process nucleosynthesis it can provide information about the time histories of these processes. The methods of using87Rb quantitatively for a chronological analysis are described. Tentative calculations based on existing experimental data are also presented. The data indicate a larger-process age than thes-process age.
