Inelastic electron interaction (attachment/ionization) with deoxyribose.
Investigation of the formation of anions and cations of deoxyribose sugar via inelastic electron interaction using a monochromatic electron beam in combination with a quadrupole mass spectrometer results have important bearing for the question of what happens in exposure of living tissue to ionizing radiation.

Electron Attachment to the Gas-Phase DNA Bases Cytosine and Thymine
We present a detailed study on dissociative electron attachment (DEA) to isolated gas-phase cytosine (C) and thymine (T). The experimental setup used for these measurements is a crossedExpand
Vibrational Feshbach resonances in uracil and thymine.
Sharp peaks in the dissociative electron attachment (DEA) cross sections of uracil and thymine at energies below 3 eV are assigned to vibrational Feshbach resonances (VFRs) arising from couplingExpand
Dissociative electron attachment to nitromethane
Abstract Dissociative electron attachment (DEA) measurements to nitromethane, CH3NO2, in the gas phase have been revisited by making use of a high mass-resolution sector field instrument. AnionExpand
Electron attachment to uracil: effective destruction at subexcitation energies.
We demonstrate that electrons at energies below the threshold for electronic excitation (<3 eV) effectively decompose gas phase uracil generating a mobile hydrogen radical and the correspondingExpand
Bond- and site-selective loss of H atoms from nucleobases by very-low-energy electrons (<3 eV).
While electrons at 1 eV result in loss of hydrogen from N1, the reaction can be switched to loss of Hydrogen from N3 by tuning the electron energy to 1.8 eV. Expand
High resolution dissociative electron attachment to gas phase adenine.
The dissociative electron attachment to the gas phase nucleobase adenine is studied using two different experiments using a double focusing sector field mass spectrometer and a hemispherical electron monochromator instrument for high electron energy resolution. Expand
Electron attachment to gas-phase uracil.
The most abundant negative ion formed via DEA is (U-H)-, where the resonance with the highest intensity appears at 1.01 eV, and the anion yield of (U,H)- shows a number of peaks, which can be explained in part as being due to the formation of different (U -H)- isomers. Expand
Structures, energetics, and dynamics of helium adsorbed on isolated fullerene ions.
Molecular dynamics simulations of C(60)He(n)(+) at 4 K show that the commensurate phase is solid, and mass spectra suggest that Commensurate layers form when all carbon hexagons and pentagons are occupied by one He each. Expand
