Collision Database for Low-T Hydrogen Plasmas

A comprehensive cross section database for collision processes between constituents of a low-temperature, low-density hydrogen plasma e, H+, H, H−, H2, H+2, H+3 is established. The processes involving electronically and/or vibrationally excited reactants or reaction products are also included in the database. The presented data information is based on critical assessment of the available experimental and theoretical data, and on the use of well established scaling relationships or relatively simple theoretical models for generation of cross sections when such were not found in the literature. All derived cross sections are represented by analytic fit functions that have physically correct energy behavior at both low (near threshold) and high collision energies. The database, however, still contains gaps for certain important state-selective collision processes required for constructing a complete H/H2 collision-radiative model.
