Inversion of Randomly Corrugated Surfaces Structure from Atom Scattering Data

摘要

The Sudden Approximation is applied to invert structural data on randomlycorrugated surfaces from inert atom scattering intensities. Several expressionsrelating experimental observables to surface statistical features are derived.The results suggest that atom (and in particular He) scattering can be usedprofitably to study hitherto unexplored forms of complex surface disorder.
