Finite Debye-Waller factor for ``classical" atom-surface scattering (bibtex)

by Kieron Burke, W. Kohn

Abstract:

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 \textrightarrow$infty$, and thus its de Broglie wavelength \textrightarrow0. We show that in this \textquoteleft\textquoteleftclassical\textquoteright\textquoteright limit, at zero temperature, the Debye-Waller factor, i.e., the probability of strictly elastic scattering (a quantum effect), tends to a finite limit (<1). We propose scattering of 20-meV Ar atoms from cold Cu(111) as a promising experiment to verify this effect, and estimate the Debye-Waller factor for this system.
