“…These methods range from the first and second Born approximations [45,46] to more advanced, fully quantum and non-perturbative treatments [47][48][49][50][51][52][53][54][55][56][57][58][59][60][61][62].…”

Time-dependent density-functional-theory investigation of the collisions of protons and α particles with uracil and adenine

et al. 2017

Time-dependent density functional theory was employed to study the e↵ects of proton and ↵-particle radiation on uracil and adenine. This method has the advantage of treating nuclear motion and electronic motion simultaneously, allowing for the study of electronic excitation, charge transfer, ionization, and nuclear motion. Particle energies were surveyed in the range of 15-500 keV for protons and 100-2000 keV for ↵-particles in conjunction with impact points both on and o↵ carbon bonds in order to investigate the electron and nuclear dynamics of irradiated molecules and the form and quantity of transferred energy. The stopping power, energy transferred, and ionization were found and the relationship between incident particle energy and electron density of to the target molecule was characterized for proton and ↵-particle radiation incident on adenine and uracil.

“…Nevertheless, most of those works focused on H + + H 2 O collisions and employed perturbative methods [17], such as the continuum-distortedwave-eikonal-initial-state (CDWEIS) [18][19][20] and first-order Born (FB) approximations [21], which are, in general, useful at impact energies E greater than 100 keV/amu. In a previous work [22], we employed the classical trajectory Monte Carlo (CTMC) method to evaluate single-ionization and singlecapture cross sections in H + + H 2 O collisions at energies 25 keV < E < 5 MeV.…”

Classical treatment of ion-H2O collisions with a three-center model potential

et al. 2011

View full text Add to dashboard Cite

We present calculations of cross sections for one-and two-electron processes in collisions of H + , He 2+ , and C 6+with water molecules in the framework of the Franck-Condon approximation. We employ an independent-electron method and a classical trajectory Monte Carlo approach. Anisotropy effects related to the structure of the target are explicitly incorporated by using a three-center model potential to describe the electron-H 2 O + interaction. We derive scaling laws with respect to the projectile charge. We also estimate cross sections for molecular fragmentation subsequent to electron removal.

“…Collisions between ions and molecules are relevant processes in cold plasmas, which have motivated a large amount of experimental [1][2][3][4][5][6][7] and theoretical [8][9][10][11][12] works.…”

“…This makes the information about their molecular structure and dynamical aspects essential for astrophysical purposes. Both of them play important roles for life, too; water is a dominant component in cells (see, e.g., [15]), and CO plays a fundamental role in the human body as a signaling molecule (most probably a neurotransmitter; see [16]); it also appears as a secondary product after DNA chain damage [8]. In particular, given the scarce information available in the literature, the study of the * pablo.martinez.martinez@uam.es † ismanuel.rabadan@uam.es interaction of carbon ions [17][18][19] as C 2+ with CO molecules is of great importance.…”

Ab initiotreatment of charge transfer in ion-molecule collisions based on one-electron wave functions

et al. 2012

View full text Add to dashboard Cite

Two simple ab initio methods based on one-electron wave functions are employed to calculate the singleelectron capture and single ionization of H 2 O and CO molecules by ion impact. The anisotropy of the molecular targets is taken into account by using multicenter pseudopotentials to represent the interaction of the active electron with the ionic molecular core. These two methods are applied to the study of three collisional systems: H + + H 2 O, He 2+ + H 2 O, and C 2+ + CO. Comparison with experiments and other theoretical works is presented when available.
