Mass accreted before critical rotation is reached (relative to initial mass) by uniformly rotating Ba star progenitors for different values of the specific angular momentum of accreted material. For progenitors with M ≥ 1.75 M addition of material with ja ≤ 5 × 1017 cm2s-1 does not result in critical rotation even for ΔM > 2 M.
