Ratio (in logarithmic scale) of the ion thermal wavelength to the WS cell volume as a function of the baryonic density n_B for the BSk24 model at four different temperatures: k_BT = 0.8 MeV (blue line), k_BT = 1.0 MeV (red line), k_BT = 1.2 MeV (green line), and k_BT = 1.4 MeV (black line). The results are obtained at beta equilibrium using the ideal-gas translational energy, Eq. (44).
