Title: Velocity map imaging of inelastic and elastic low energy electron scattering in organic nanoparticles

Abstract

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 study, 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.

Differential inelastic electron scattering cross sections from experimental reflection electron-energy-loss spectra: Application to background removal in electron spectroscopy

Journal Article Tougaard, S ; Chorkendorff, I - Phys. Rev. B: Condens. Matter; (United States)

The possibility of extracting absolute inelastic electron scattering cross sections K(T) (differential in energy loss T and path length) for solids from experimental electron spectra is studied. Assuming homogeneous scattering properties for the solid, a formula is found, which allows a direct determination of (lambdaL/(lambda+L))K(T) from a measured reflected electron-energy-loss spectrum (REELS) resulting from a monoenergetic beam of electrons incident on the surface of the solid. Here lambda is the inelastic electron mean free path and Lapprox. =2lambda/sub 1/ where lambda/sub 1/ is the transport mean free path for elastic electron scattering. The formula is applied to experimental REELS spectramore »« less

A moment-preserving nonanalog method for charged particle transport.

Conference Prinja, Anil K ; Franke, Brian Claude ; Fichtl, Erin ; ...

Extremely short collision mean free paths and near-singular elastic and inelastic differential cross sections (DCS) make analog Monte Carlo simulation an impractical tool for charged particle transport. The widely used alternative, the condensed history method, while efficient, also suffers from several limitations arising from the use of precomputed smooth distributions for sampling. There is much interest in developing computationally efficient algorithms that implement the correct transport mechanics. Here we present a nonanalog transport-based method that incorporates the correct transport mechanics and is computationally efficient for implementation in single event Monte Carlo codes. Our method systematically preserves important physics and ismore »« less
ELASTIC AND INELASTIC SCATTERING OF K$sup +$-PARTICLES IN NUCLEAR EMULSIONS

Journal Article Kristiansson, K - Arkiv Fysik

The frequency of elastic and inelastic K/sup +/ particle scattering and the energy loss in inelastic scattering have been studied at a K particle energy of 80 to 120 Mev. 32.5 m K particle track has been followed. The frequency of elastlc scatterings in the angular interval 12 to 20 deg indicates a rePulsive nuclear potential of about 10 Mev if the optical nuclear model is used. The mean free path for inelastic scattering (including charge exchange events) is equal to 1.12 plus or minus 0.23 m, corresponding ta a total cross section of 181 plus or minus 37 mb.more »« less
Elastic and inelastic scattering of 100 MeV protons from the even-even titanium isotopes

Journal Article Woo, L W ; Wall, N S ; Roos, P G ; ... - Phys. Rev. C; (United States)

The differential cross sections for elastic and inelastic scattering to the first excited (2/sup +/) states of 100 MeV protons from /sup 46,48,50/Ti were measured. The angular ranges covered were 9/sup 0/ to 110/sup 0/ for /sup 46,50/Ti and 9/sup 0/ to 168/sup 0/ for /sup 48/Ti. The elastic scattering data were analyzed with a local optical model potential. The quality of fits to the data covering the smaller angular range (<110/sup 0/) is good for all three isotopes, with chi/sup 2//Napprox.1.5; whereas the fit to the large angle data of /sup 48/Ti (< or approx. =168/sup 0/) is notmore »« less

The relative importance of elastic and inelastic scattering in angle-resolved Auger electron spectroscopy - A response to ADAM

Journal Article Chambers, S A - Langmuir; (USA)

The importance of elastic scattering and interference in creating the modulation observed in angle-resolved Auger electron spectroscopy is discussed, along with the conceptual similarity between the scattering of auger and photoelectron waves. While inelastic scattering is certainly important, the angular dependence of the associated cross sections is considerably less pronounced than that associated with elastic scattering. These results, which have been firmly established in the past decade, are at odds with recent claims by Frank et al.
