Low-energy electron scattering from DNA and RNA bases: shape resonances and radiation damage.
نویسندگان
چکیده
Calculations are carried out to determine elastic-scattering cross sections and resonance energies for low-energy electron impact on uracil and on each of the DNA bases (thymine, cytosine, adenine, and guanine), for isolated molecules in their equilibrium geometry. Our calculations are compared with the available theory and experiment. We also attempt to correlate this information with experimental dissociation patterns through an analysis of the temporary anion structures that are formed by electron capture in shape resonances.

Resonant channel coupling in electron scattering by pyrazine.
Detailed investigation of the three low-energy resonances seen in electron scattering by the diazabenzene molecule pyrazine reveals that the first two are nearly pure single-channel shape resonances, but the third is, as long suspected, heavily mixed with core-excited resonances built on low-lying triplet states. Such resonant channel coupling is likely to be widespread in pi-ring molecules, in...
متن کاملLow-energy electron scattering with the purine bases of DNA/RNA using the R-matrix method.
R-matrix calculations on electron collisions with the purine bases found in DNA and RNA (i.e., adenine and guanine) are presented. Resonant anion states of these systems are identified by employing different approximation levels of ab initio theoretical methods, such as the static exchange, the static exchange plus polarization, and the close-coupling methods. The results are compared with othe...
متن کاملDiffraction in resonant electron scattering from helical macromolecules: A- and B-type DNA
We elaborate our theoretical framework to treat low-energy electron scattering from helical macromolecules. A model of simple scatterers organized into a helical structure is proposed with application to base-pair arrangements in DNA. We extend our analysis to A-type DNA as well as nonperiodic arrangements in B-type DNA. Diffraction patterns due to base-pair spacing are observed under all condi...
متن کاملLow-energy electron scattering by pyrazine
We report cross sections for low-energy elastic electron collisions with the diazabenzene molecule pyrazine, obtained from first-principles calculations. The integral elastic cross section exhibits three sharp peaks that are nominally shape resonances associated with trapping in the vacant * molecular orbitals. Although the two lowest-energy resonances do in fact prove to be nearly pure single-...
متن کاملInteractions of Slow Electrons with Biomolecules
We report on results of computational studies of the interaction of slow electrons with the purine and pyrimidine bases of DNA, as well as with their associated nucleosides and nucleotides. The calculations focus on characterisation of the π∗ resonances associated with the bases and also provide general information on the scattering of slow electrons by these targets. High-level studies of the ...
