Comparison between different models of the variation surface abundances of 3He, 7Li, 12C, and C-isotopes ratio. The models with different values of Λe = 0.5, 0.6, and αth = 0, 50, 100, 150 by using solar-scaled and [α/Fe] = 0.4 mixtures are shown according to the indicated labels. For simplicity, only the evolution during the red giant phase is shown here.
