Electron attachment to the DNA bases thymine and cytosine

Electron attachment (EA) to the DNA bases thymine (T) and cytosine (C) was studied in the
electron energy range from about 0 to 9 eV using a crossed electron/molecule beams
technique. As uracil the dominant negative ions formed via EA reactions to T and C are (T−
H)−(corresponding to T minus H, with a mass to charge ratio of 125) and (C−
H)−(corresponding to C minus H with a mass to charge ratio of 110). The respective partial
EA cross-sections for (T− H)− and (C− H)− could be determined yielding peak values of σ …
