Rate coefficients for rovibrational transitions in H_2 due to collisions with He
arXiv:astro-ph/9904376 · doi:10.1086/307846
Abstract
We present quantum mechanical and quasiclassical trajectory calculations of cross sections for rovibrational transitions in ortho- and para-H_2 induced by collisions with He atoms. Cross sections were obtained for kinetic energies between 10^-4 and 3 eV, and the corresponding rate coefficients were calculated for the temperature range 100<T<4000 K. Comparisons are made with previous calculations.
