accommodation coefficient

[ə‚käm·ə′dā·shən ‚kō·ə′fish·ənt]
(statistical mechanics)
The ratio of the average energy actually transferred between a surface and impinging gas molecules scattered by the surface, to the average energy which would theoretically be transferred if the impinging molecules reached complete thermal equilibrium with the surface.
