title: Temperature Dependence of the Dissociative Electron Attachment to 2-Thiothymine.
abstract: We report the temperature dependence for the dissociation of 2-thiothymine induced by low energy electrons. Although hot molecules favor dissociative electron attachment (DEA) initiated by shape/core-excited resonances, here we demonstrate that, in contrast, the dipole bound mediated DEA is inhibited, by decreasing the accessibility for the excess electron to the dipole bound anion formation channel. In addition, from this research the estimation of the change in the cross sections for the fragments production via the shape/core-excited resonances can be extended to temperatures at biological relevance.
