δ(92Zr/94Zr) model predictions for the D1.5 case of a 2 M, 0.5 Z AGB star at the 7th TP (when the convective envelope becomes carbon-rich) and 25th TP (the last TP during the AGB phase) are plotted against the 13C-pocket mass for Three-Zone_d2 to Three-Zone_p2, and Zone-II_d2.5 to Zone-II_p2 models.
