Description
We have carried out a detailed abundance analysis for 21 elements in a sample of 27 stars with a wide range in luminosity from luminous giants to stars near the main-sequence turnoff in the globular cluster M13 ([Fe/H]=-1.50dex) and in a sample of 13 stars distributed from the tip to the base of the red giant branch (RGB) in the globular cluster M3 ([Fe/H]=-1.39dex). The analyzed spectra, obtained with HIRES at the Keck Observatory, are of high dispersion (R={lambda}/{Delta}{lambda}=35000).
