Supplementary material for "Inverse bremsstrahlung absorption and ion stopping in prescribed super-Gaussian electron distributions": code, data and validation records

This record contains the supplementary material for the article "Inverse bremsstrahlung absorption and ion stopping in prescribed super-Gaussian electron distributions" by Manal M. Al-Ali, Anas M. Ababneh and Ahmed Al-Khateeb, submitted to the Journal of Plasma Physics. It includes the Python source code, the numerical data behind all figures and tables, and the validation records. The code computes the collisionless dielectric response, the inverse bremsstrahlung structural factors, the electronic stopping power and its sensitivity to the wavenumber cutoff. It does this for prescribed isotropic super-Gaussian electron distributions (2 ≤ m ≤ 5) in a DT plasma at nₑ = 5 × 10²³ cm⁻³ and Tₑ = 500 eV. All verification checks passed, and an independent implementation agrees with the production solver to within 10⁻¹¹ relative difference at the benchmark points. The package was tested with Python 3.12, NumPy, SciPy and Matplotlib; the README gives full instructions for reproducing the results.
