ISICS, originally a C language program for calculating K-, L-and M-shell ionization and X-ray production cross sections from ECPSSR and PWBA theory, has been reengineered into a C++ language class, named ISICSoo. The new software design enables the use of ISICS functionality in other software systems. The code, originally developed for Microsoft Windows operating systems, has been ported to Linux and Mac OS platforms to facilitate its use in a wider scientific environment. The reengineered software also includes some fixes to the original implementation, which ensure more robust computational results and a review of some physics parameters used in the computation. The paper describes the software design and the modifications to the implementation with respect to the previous version; it also documents the test process and provides some indications about the software performance. Ionization and X-ray production cross section calculations for ion-atom collisions. Solution method: Numerical integration of form factor using a logarithmic transform and Gaussian quadrature, plus exact integration limits. Reasons for the new version: Capability of using ISICS physics functionality in other software systems; porting the software to other platforms than Microsoft Windows; improved computational robustness and performance. Summary of revisions: Reengineering into a C++ class; several internal modifications to improve correctness and robustness; updated binding energies tabulations; performance improvements. Running time: The running time depends on the selected atomic shell and the number of polynomials used in the Gaussian quadrature integration.

“…The effects of different binding energies on the accuracy of proton ionization cross sections have been evaluated by comparing values based on various binding energy collections with experimental data for K and L shells. The experimental data derive from the reviews by Paul and Sacher [171], Sokhi and Crumpton [172] and Orlic et al [173]; the comparison process adopts the same strategy described in [43] for the validation of the cross section models available in Geant4. For each element, the compatibility between calculated and experimental cross sections is evaluated by means of the χ 2 test; the significance of the test for the rejection of the null hypothesis of The analysis of the sensitivity to electron binding energies is reported here for plain ECPSSR cross sections.…”

A survey of atomic binding energies used by general purpose Monte Carlo systems is reported. Various compilations of these parameters have been evaluated; their accuracy is estimated with respect to experimental data. Their effects on physics quantities relevant to Monte Carlo particle transport are highlighted: X-ray fluorescence emission, electron and proton ionization cross sections, and Doppler broadening in Compton scattering. The effects due to different binding energies are quantified with respect to experimental data. The results of the analysis provide quantitative ground for the selection of binding energies to optimize the accuracy of Monte Carlo simulation in experimental use cases. Recommendations on software design dealing with these parameters and on the improvement of data libraries for Monte Carlo simulation are discussed.
