Flow chart in the Pb–Rn region in the MAϵ4α04 model, at maximum neutron density (N_n = 2.17 × 10¹⁵ cm⁻³). The coloured arrows from a given isotope, i, represent the flux ratio F/F_tot, where F corresponds to the flux of the (n, γ) reaction F_(n, γ) = N_avρY_nY_i⟨σv⟩, β decay F_β = λ_βY_i, or α decay F_α = λ_αY_i, and F_tot = F_(n, γ) + F_β + F_α (Y_n and Y_i being the molar mass fraction of the neutrons and target, respectively, ⟨σv⟩ the nuclear reaction rate, and λ_β and λ_α the decay rates). The yellow area shows the nuclei experiencing α decays with t_1/2 <  1 s.
