Averaged final mass fraction ratio Mn/Cr as a function of the initial neutron excess. The average mass fractions are drawn either from the fit to the distribution of maximum temperatures given in the left panel of Fig. 3 (red circles) or from a uniform distribution function representative of the models shown in the right panel of the same figure (blue crosses). In both cases, the results are shown for different τ_rise in the range 10^-9−0.2 s, τ in the range 0.10−0.90 s, and X(¹²C) in the range 0.3−0.7. The solid line is a fit given by, M(Mn)/M(Cr) = 49.1η^0.676. The dashed line shows the relationship expected from an analytic model, Eq. (17). Green stars give the mass fraction ratio Mn/Cr for high-entropy conditions (see text for details).
