jaxrts.ionization.saha_equation(gi: float, gj: float, T_e: Quantity, energy_diff: Quantity) → Quantity

Classic (non-degenerate) Saha balance relation.

Returns \(n_{i+1} n_e / n_i\):

\[\frac{n_{i+1}n_e}{n_i} = 2\frac{g_j}{g_i} \frac{(2\pi m_e k_B T_e)^{3/2}}{h^3} \exp\!\left(\frac{-\Delta E}{k_B T_e}\right)\]

Parameters:

• gi (float) – Statistical weights of the lower and upper states.

• gj (float) – Statistical weights of the lower and upper states.

• T_e (Quantity) – Electron temperature.

• energy_diff (Quantity) – Ionization energy \(\Delta E\).
