Abstract:
Elemental abundances are derived for four sharp-lined stars, the
Mercury-Manganese stars µ Lep, HR 4817, and 28 Her, and 7 Sex,
a Population I star with Population II space motions, using REOSC
echelle spectrograms obtained at CASLEO to extend previous studies.
Comparisons with published equivalent widths indicate that the CASLEO
scale is marginally larger than those of DAO Reticon and KPNO CCD
spectra. The CASLEO spectrograms have improved the quality of the
abundance determinations. New abundances are found for a few elements.
