"Solid-state amorphous systems display no long-range atomic order as is seen in crystals, but do have a subtle local atomic structure that can be studied statistically. The structure of amorphous systems can be most completely understood by looking at the problem from a variety of experimental perspectives. We have probed the sub-nanometer (short range) atomic structure of a model metallic glass system using resonant x-ray scattering (also known as anomalous scattering), a technique that yields element-specific short range structural formation. This same palladium-based glass system was also probed
by fluctuation electron microscopy, an electron scattering technique that is sensitive to nanometer-scale (medium range) atomic structure.
Reverse Monte Carlo computer simulations using the x-ray data together with fluctuation electron microscopy simulations can be used to begin to unravel some of the structural themes in glass systems."

The resonant scattering work we did at SSRL involved working with the Pd Ni P amorphous metal system. We did experiments at x-ray energies near the Pd and Ni edges to get a look at the local atomic environment around these atoms.
