Compilation of cross sections for kinetic models of low pressure hydrogen discharges

We report an initial compilation of cross sections that have been used to model\footnote{A. V. Phelps, {\it Phys. Rev. E} {\bf 79}, 066401 (2009).}$^,$\footnote{A. V. Phelps, {\it Plasma Sources Sci Technol.} {\bf 20}, 043001 (2011).} the collisional kinetics of low-pressure discharges in H$_2$. Processes that are considered include electron momentum transfer, excitation, and ionization collisions with H$_2$; momentum transfer, H$_\alpha$ excitation, ionization, and charged pair formation in collisions of H$^+$, H$_2^+$, H$_3^+$, H, H$_2$,and H$^-$ with H$_2$; collisions of electrons, H$^+$, H$_2^+$, H$_3^+$, H, H$_2$, and H$^-$ with graphite and Cu surfaces resulting in secondary electrons, particle reflection, and negative ion formation. For each major category, the compilation includes a section reviewing data sources. The recommendations are expressed as analytic formulas expected to be good to $\pm 10\%$. This compilation is expected to be refined from time to time. As part of the Plasma Data Exchange Project, the compilation will be made available at http://www.lxcat.laplace.univ-tlse.fr/ and/or http://www.icecat.laplace.univ-tlse.fr/.
