Abstract
We present the results of quantum mechanical calculations of cross sections and hence rate coefficients for rovibrational transitions in ortho- and para-, induced by collisions with He. Rovibrational levels up to were included in the calculations, and rate coefficients are available for temperatures . Comparison is made with previous calculations of rate coefficients for pure rotational transitions within the vibrational ground state and with measurements of the rate coefficient for vibrational relaxation at both high and low temperatures. Agreement is found to be good.Keywords
