Abstract
The electron inelastic mean free path (IMFP) of molybdenum is determined experimentally over an energy range of 1-120 eV using analysis of X-ray absorption fine structure (XAFS). This new approach enables accurate measurements of IMFPs in this energy range where direct measurements are often difficult and highly uncertain, and provides a means for studying materials inaccessible through current alternate techniques. This approach can also be used to determine localized IMFPs within complex molecular systems, enabling detailed study of surfaces and nanoenvironments. This information is important for diverse applications in physical chemistry including electron microscopy, spectroscopy, and di..
