  Electron transport is of fundamental importance, and has application in a
variety of fields. Different scattering mechanisms affect electron transport in
solids. It is important to comprehensively understand these mechanisms and
their scattering cross-sections to predict electron transport properties.
Whereas electron transport is well understood for high kinetic energy (KE)
electrons, there are inconsistencies in the low KE regime. In this work,
velocity map imaging soft X-ray photoelectron spectroscopy is applied to
unsupported organic nanoparticles to extract experimental values of inelastic
and elastic mean free paths. The obtained data is used to calculate
corresponding scattering cross-sections. The data demonstrates a decrease of
the Inelastic Mean Free Path and increase of the Elastic Mean Free Path with
increasing electron KE between 10-50 eV.
