Rubidium and Lead Abundances in Giant Stars of the Globular Clusters M4 and M5

Yong, David; Lambert, David L; Paulson, D.B.; Carney, B W


We present measurements of the neutron-capture elements Rb and Pb for bright giants in the globular clusters M4 and M5. The clusters are of similar metallicity ([Fe/H] ≃ -1.2), but M4 is decidedly s-process enriched relative to M5: [Ba/Fe] = +0.6 for M4
