Total Cross Sections For Dissociative Electron Attachment in Dichloroalkanes and Selected Polychloroalkanes: The Correlation With Vertical Attachment Energies

Rovibrationally enhanced dissociative electron attachment to molecular lithium.

Wadehra JM. Rovibrationally enhanced dissociative electron attachment to molecular lithium. We have investigated the role played by initial rovibrational excitation of Liz on the cross sections and rates for dissociative electron attachment to the molecule. For a given internal energy, the vi-brational excitation enhances the attachment cross section more than the rotational excitation, The att...

Detection of new dissociative electron attachment channels in NO.

Three dissociative electron attachment channels have been detected and identified in NO via measurement of the O(:P) fragment energy. In addition to the known N(2D °) + O (2p) channel, two new channels N(4S °) + O (2p) and N(2P °) + O (2p) were detected. Cross sections for each of the channels are reported by normalizing the scattering intensities to previously measured total cross sections. Th...

Absolute dissociative electron attachment cross sections in acetylene and its deuterated analogue.

An instrument for the measurement of absolute dissociative electron attachment cross sections was constructed and applied to two prototype molecules, acetylene (C2H2) and deuterated acetylene (C2D2). The isotope effect at the first dissociative electron attachment band at 3 eV was determined--the cross section for C2D-/C2D2 is 14.4 times smaller than that for C2H-/C2H2. The results play a centr...

Nanoscopic models for radiobiological damage: metastable precursors of dissociative electron attachment to formic acid F A Gianturco and R R Lucchese Total and positronium formation cross sections for positron scattering from H2O and HCOOH

We report experimental results for electron scattering from formic acid (HCOOH). A set of differential cross-sections is provided for elastic scattering at incident electron energies from 1.8 to 50 eV. Integral and momentum transfer cross-sections have also been derived from these results. Our results are compared, where possible, with recent theoretical calculations.
