Scientific paper

Rates for rotational excitation of water molecules in collisions with He
atoms have been obtained from a new, accurate theoretical interaction
potential. Rates among the lowest 40 ortho levels are given for kinetic
temperatures to 1400K and among the lowest 29 para levels for kinetic
temperatures to 800K.
