TL;DR: Using high-quality gas phase electron scattering calculations and multiple scattering theory, the authors attempted to gain insights on the radiation damage to DNA induced by secondary low-energy electrons in the condensed phase, and to bridge the existing gap with the gas phase theory and experiments.

TL;DR: In this article, the electron-stimulated desorption (ESD) of D- and H- ions from condensed D20 and H20 films is investigated, and three lowenergy peaks are observed in the ESD anion yield, which are identified as arising from excitation of 2B1, 2A1 and 2B 2 dissociative electron attachment (DEA) resonances.

TL;DR: In this article, a model of simple scatterers organized into a helical structure is proposed with application to base-pair arrangements in DNA, and the role of electron diffraction in electron attachment to the bases leading to the formation of shape and core-excited resonances.

TL;DR: An absolute cross section for strand-break damage by 10 eV electrons and inelastic scattering attenuation length in DNA-Dap complex films is determined using a well-adapted deterministic survival model for the variation of electron damage with fluence and film thickness.

TL;DR: The maxima in the present cross sections are found to correspond to the resonances that have been reported at about the same energies in the O- yield from electron impact on thymine in the gas phase.
