Electron capture from molecular targets impacted by swift ions, H + , He 2+ , Li 3+ and C 6+ , is investigated in the framework of the quantum-mechanical continuum distorted wave-Eikonal initial state model. Biological molecules considered are nitrogen, methane, carbon monoxide, carbon dioxide and water. In particular, for water, the calculation of the corresponding cross sections plays a fundamental role for the determination of energy deposition in biological matter. A detailed analysis on the contributions coming from different molecular orbitals to total cross sections (TCS) are discriminated as well as those of capture to fundamental and excited projectile states. A good agreement with measurements is found for cases where experimental data exist. For other systems, the theoretical results here reported are useful for the prediction of the corresponding TCS.

Whether it is in radiobiology to identify DNA lesions or in medicine to adapt the radiotherapeutic protocols, a detailed understanding of the radiation-induced interactions in living matter is required. Monte Carlo track-structure codes have been successfully developed to describe these interactions and predict the radiation-induced energy deposits at the nanoscale level in the medium of interest. In this work, the quantum-mechanically based Monte Carlo track-structure code TILDA-V has been used to compute the slowing-down of protons in water and DNA. Stopping power and range are then reported and compared with existing data. Then, a first application of TILDA-V to cellular irradiations is also reported in order to highlight the absolute necessity of taking into account a realistic description of the cellular environment in microdosimetry.

Proton-proton elastic scattering has been measured by the TOTEM experiment at the CERN Large Hadron Collider at √s = 7 TeV in special runs with the Roman Pot detectors placed as close to the outgoing beam as seven times the transverse beam size. The differential cross-section measurements are reported in the |t|-range of 0.36 to 2.5 GeV2. Extending the range of data to low t values from 0.02 to 0.33 GeV2, and utilizing the luminosity measurements of CMS, the total proton-proton cross section at √s = 7 TeV is measured to be (98.3 ±0.2stat ±2.8syst) mb.

In the current work, we investigate the ionization of water molecules impacted by neutral hydrogen and proton beams. The continuum distorted wave-eikonal initial-state approximation is used to describe the reaction. Differential and total cross sections are compared with the available experimental data and a fine analysis of the influence of the projectile charge state on the ionization process is reported.

In collisions involving projectiles with bound electrons, partial or total screening of their nuclear charge must be considered. Accordingly, a projectile dynamic effective charge, as a function of the collision momentum transfer, is included in the state-of-the-art continuum distorted wave with eikonal initial state model. This correction, applied in the exit channel, recovers a two-center description from collisions with neutral projectiles. Also, an improvement of both target and projectile ionization double differential cross sections is achieved, especially at the binary encounter and electron capture to the continuum peaks. The results calculated by our analytical model are shown in accordance with previous theoretical and experimental work.

In this work, a dynamic charge is employed in the continuum distorted wave–eikonal initial state theoretical model to describe the non-Coulomb potential of the residual target for single ionization in bare ion–multielectron atom collisions. A comparison between the well-known Belkić prescription and the effective charge depending on emission angle and energy in the final residual-target continuum state is shown. The obtained results show that this effective charge improves the description of double-differential cross sections for backward emission angles over the whole emission energy range allowing the calculation of simple differential and total cross sections.
