A free-parameter theoretical model for describing the electron elastic scattering in water in the Geant4 toolkit

Geant4‐DNA example applications for track structure simulations in liquid water: A report from the Geant4‐DNA Project

“…No angular deflection is considered in collisions leading to electronic excitation. The elastic cross sections are based on partial wave calculations, considering a total interaction potential which takes into account a static contribution as well as fine effects, like exchange and polarization contributions . No energy loss is considered to take place in elastic collisions.…”

“…The elastic cross sections are based on partial wave calculations, considering a total interaction potential which takes into account a static contribution as well as fine effects, like exchange and polarization contributions. 57 No energy loss is considered to take place in elastic collisions. Finally, the "option 2" constructor also takes into account the vibrational excitation and electron attachment processes which apply to electrons with kinetic energy lower than the lowest excitation level of liquid water (8.22 eV).…”

Calculation of direct effects of 60Co gamma rays on the different DNA structural levels: A simulation study using the Geant4-DNA toolkit

“…Ionization and electronic excitation cross-sections can be applied for electrons with energies from 8.22 eV to 1 MeV [45,46]. For electrons with energies below 8.22 eV, elastic scattering, vibrational excitation and attachment are taken into account [47].…”

On the consistency of Monte Carlo track structure DNA damage simulations

“…37 The ROI and LEPR are centered in the water slab, which is a cube with sides of 1 cm. The LEPR is a virtual volume surrounding the ROI in which the following Geant4-DNA models and processes, from the G4EMLOW6.23 data file, were active: Champion elastic, 38 Born ionization and excitation (see details in Ref. 18), Melton attachment, and Sanche excitation.…”
