  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, [ls/Fe], of ~+0.6 dex and heavy s-process elements,
[hs/Fe], of ~+0.3 dex were determined for all the giant stars. There was no
statistically significant difference between the abundances determined for the
Red Giant Branch (RGB) and AGB stars in this study. The results for the RGB
stars differ from those obtained by a number of previous studies. However,
because of the similar abundance results obtained for the AGB and RGB stars in
this study we believe this provides evidence for previous enrichment of the
material from which these stars formed.
