jaxrts.ipd.ipd_debye_hueckel(Zi: float, ne: Quantity, ni: Quantity, Te: Quantity, Ti: Quantity, Zbar: float | None = None, arb_deg: bool = False) → Quantity[source]

The correction to the ionization potential for the m-th ionization stage in Debye-Hueckel approximation.

Note

The Debye-Hueckel approximation is physically meaningful only when the coupling parameter << 1, such that Coulomb forces are weak perturbations.

Parameters:

  • Zi – The charge state of the atom (note that this is the state before the ionization).

  • ne – Electron density. Units of 1/[length]**3.

  • ni – Ion density. Units of 1/[length]**3.

  • Te – The electron temperature.

  • Ti – The ion temperature.

  • arb_deg (bool, default false) – If True the Debye screening length is evaluated using inverse_screening_length_e(), which includes solving the Fermi integral, rather than the classical value.

Returns:

Quantity. – The ipd shift in units of electronvolt.
