Parameters for calculating two-photon continuum for hydrogen-like ions

Notes

The parameter :math: psi_{text{norm}} (called :math: A_{text{sum}} in CHIANTI) is a normalization factor of

the integral of the spectral distribution function \(\psi(y)\) from 0 to 1, such that :math: frac{1}{psi_{text{norm}}} int_{0}^{1} psi(y) dy = 2. This normalization is only used For hydrogenic ions.
