SCATTERING OF NEUTRAL ATOMS BY AN EXPONENTIAL CORRUGATED POTENTIAL

The integral equation of the scattering is solved exactly for a one-dimensional exponential corrugated potential. Numerical results are presented for a sinusoidal and a triangular profile of small amplitude. As the slope" of the exponential increases the intensities given by the hard corrugated wall are approached. The finite slope of the potential has the strong effect of forcing the particles into the specular peak and tends to reduce the effect of multiple scattering. © 1979 The American Physical Society."
