Averaged final mass fraction ratios of vanadium to titanium and of manganese to titanium as tracers of the initial neutron excess. The meaning of the point types and colors, as well as the ranges of parameters are the same as in Fig. 9. Left: mass ratio V/Ti. The solid line is a fit given by, M(V)/M(Ti) = 14.8η^0.73. The dashed line shows the relationship expected from an analytic model, Eq. (19). Right: mass ratio Mn/Ti. The solid line is a fit given by, M(Mn)/M(Ti) = 1170η^0.68. The dashed line shows the relationship expected from an analytic model, Eq. (21).
