This research forms part of an investigation into heavy-element abundances in asymptotic giant branch (AGB) stars in various stellar environments. Seven giant stars in the southern globular cluster 47 Tuc have been observed using the Anglo-Australian Telescope. Abundances for five s- and r-process elements have been determined: the light s-process elements Y and Zr, the heavy s-process elements La and Nd, and the r-process element Eu. Mean enhancements in the light s-process elements, [ls/Fe… Expand
