Scientific paper

A program of stellar Ti isotopic-abundance determinations is described and related to changes that may have occurred in the Ti isotopic abundance ratios during the chemical evolution of the Galaxy, and to whether the abundance ratios are perturbed in the S and MS stars having atmospheres with enhanced abundances of s-process nuclei resulting from convective mixing after internal exposure to neutrons. High-resolution (0.07 A) Reticon spectra of portions of the TiO gamma (0,0), gamma (0,1), and delta (0,0) bands were the source material, and particular emphasis was placed on the definition of the continuum level. The isotopic abundance ratios are terrestrial in all of the sample, and errors in the (Ti-i)/(Ti-48) ratio are typically plus or minus 25% for the dwarfs and plus or minus 50% for the giants. The observations show that the magic nucleus Ti-50 is not enhanced in S and MS stars.
