      abstract     = {Low energy ion scattering is a technique to detect the
                      energy of ions which are scattered from a surface. For noble
                      gas ions, it is predominantly sensitive to the topmost
                      surface layer due to strong neutralisation processes.
                      Depending on the combination of projectile ion and target
                      material, the scattering spectra can exhibit contributions
                      resulting from multiple scattering processes in deeper
                      layers when probing ions are re-ionised on the exiting
                      trajectory. These events cause a pronounced continuum
                      located toward lower scattering energies with respect to the
                      direct scattering peak. In a previous work a semi-empirical
                      formula has been given which allows fitting and derivation
                      of quantitative information from the measured spectra
                      [Nelson 1986 J. Vac Sci. Technol. A 4 1567-1569]. Based on
                      the former work an improved formula is derived which has
                      less numerical artefacts and is numerically more stable.},
