Inelastic atom-surface scattering by phonons: A comparison of different approaches
Article Abstract:
A comparison of exponentiated Born approximation (EBA) for the scattering by an Einstein-model with two types of coherent state approximations and with the results of an exact coupled channel calculation is presented. The study further calculates elastic and inelastic scattering cross sections, elastic scattering phase shifts, wave functions and classical trajectories.

Inverse scattering theory: strategies based on the Volterra inverse series for acoustic scattering
Article Abstract:
The necessity of half-off-shell transition-matrix elements (near-field) information on iterative approaches to the inverse acoustic scattering problem is discussed. It is shown that the recently introduced Volterra inverse series correctly predicts the first two moments of the interaction, while the Fredholm inverse series is correct only for the first moment.

Rayleigh and Raman scattering from individual carbon nanotube bundles
Article Abstract:
Rayleigh scattering spectra and Raman spectra from single bundles of aligned single-wall carbon nanotubes are obtained with dark filed optical microscopy and Raman microscopy. Tangential mode Raman spectrum from metallic nanotubes showed more variation from bundle to bundle than that from semi conducting tubes.
