We consider atom-surface scattering at low surface temperature, fixed incident energy and fixed interaction potential. We examine the limit as the mass m of the incident particle, and thus its de Broglie wavelength. We show that in this classical limit, the Debye-Waller factor a quantum effect for the strictly elastic scattering amplitude tends to a finite limit. We propose scattering of 20 MeV Ar atoms from cold Cu111 as a promising experiment to verify this effect.
