|Title:||Theory of nuclear resonant inelastic scattering from 57Fe in a single-walled carbon nanotube|
|Published:||January 01, 2007|
|Abstract:||Line shapes of one phonon lines are calculated in the nuclear resonant inelastic X-ray scattering (NRIXS) from 57Fe embedded in a single-walled carbon nanotube using a computationally efficient phonon Green's function method which is also applicable to other nanostructures. The line shapes are anisotropic and have some unusual features which can provide a new insight into the physical processes in nanomaterials at atomistic scales and can be used to characterize them. In particular, the line shapes in certain directions can be used to determine the chirality of a nanotube for which no direct and convenient method is available.|
