WebApr 12, 2024 · Weak freeze-out occurs at T f ≃ 0.84 MeV, and corresponds to a flattening of the neutron and proton curves in Figure 4. At freeze-out, the neutron-to-proton ratio is given approximately by the Boltzmann factor, (n / p) f ≃ e − Δ m / T f ∼ 1 / 4.66, where Δ m = m n − m p = 1.293 MeV is the neutron–proton mass difference.
