Determination of electron collision of cross-sections for the H ₂ molecule for plasma discharge simulation

Momentum transfer cross-section, rotational cross-sections, vibrational cross-sections, and electronic excitation cross-sections for H ₂ molecule for plasma discharge simulation have been determined from measured and calculated electron transport coefficients in H ₂-Ar mixtures and in pure H ₂ gas at 293K using the electron swarm study and the two-term approximation Boltzmann solution for energy. The set of electron collisions cross-sections for H ₂ molecule reproduced the experimental transport coefficients in pure H ₂ gas and in 0.5% and 4% H ₂-Ar mixtures. The reproduced transport coefficients such as electron drift velocity (W), longitudinal diffusion coefficient per mobility ratio (DL/μ), transverse diffusion coefficient per mobility ratio (DT/μ) and ionization coefficient per density ratio (α/N) in pure H ₂ gas and W, DT/μ in H ₂-Ar mixtures were within ±5% deviation from experimental results. The cross-section set also yielded drift velocity in 10.91% H ₂-He mixture within 0-2%.
