## [124.08] WIYN Open Cluster Study: The Evolution of the Lithium-Rotation Anticorrelation in Young Cluster F Stars

A. Steinhauer, C. P. Deliyannis (Indiana University)

We present new lithium and v \sin i data for F stars in clusters with ages between the Pleiades and Hyades, and find a strong correlation between the age of the cluster and a) the slope of the trend in this plane, and b) the maximum observed v \sin i for each cluster. We discuss the implications for the mechanisms responsible for the formation of the Li Gap''. We gratefully acknowledge support from the National Science Foundation under grant AST 02-06202.
