The collision-induced dissociation process in He + H-2 is Studied quan
tum mechanically using the infinite-order sudden approximation. The di
ssociation cross sections for the initial vibrational states nu = 0-9
are reported in a wide range of the total energy 5-10 eV and the rate
constants are calculated in the temperature range 1000-10000 K. The di
ssociation cross sections are strongly dependent on nu. It is found th
at the details of interaction potential strongly affect the dissociati
on dynamics for low nu. The reliability of the classical trajectory me
thod is discussed. (C) 1998 Elsevier Science B.V. All rights reserved.
