QSE cluster motion in the chart of nuclides for an α-rich freeze-out. The QSE cluster remnant condenses near the magic number 28. Each colored line corresponds to a nuclear reaction and indicates the level of nuclear flow transferred between the isotopes connected. Normalized flows ϕ are colored black for 0 ⩽ ϕ < 0.01, navy for 0.01 ⩽ ϕ < 0.05, blue for 0.05 ⩽ ϕ < 0.1, cyan for 0.1 ⩽ ϕ < 0.4, green for 0.4 ⩽ ϕ < 0.8, red for 0.8 ⩽ ϕ < 1.0, and yellow for ϕ = 1.0. Small ϕ values indicate reactions in equilibrium, while ϕ = 1.0 implies pure one-way nuclear flow transfer.
