Mg isotopic ratios in giant stars of the globular cluster NGC 6752
Yong, David; Grundahl, Frank; Lambert, David L; Nissen, Poul E; Shetrone, M.D.
Mg isotopic abundance ratios are measured in 20 bright red giants in globular cluster NGC 6752 based on very high-resolution (R ∼ 110 000), high signal-to-noise spectra obtained with UVES on the VLT. There is a considerable spread in the ratio 24Mg:25Mg
