Transition to the Newtonian regime for different alphas in family. Vertical dashed lines, from left to right, mark values β ≡ g^N/a₀ = 1.20, 2.10 and 2.75, respectively. These came from , using α = 0.5, a₀ = 1.2 × 10^-10 m s^-2 (β = 1.20); α = 0.5, a₀ = 8.11 × 10^-11 m s^-2 (β = 2.10); α = 1.5, a₀ = 8.11 × 10^-11 m s^-2 (β = 2.75), and assuming that the external field dominates over the internal, . When this is not the case the values of β are even larger. Note that . g_e is always the same constant , but what matters is that the value of g_e varies in units of a₀ as one varies a₀.
