Allan, Michael 2007-03-21 Processes induced by the attachment of slow electrons to formic acid and its hydrogen-bonded dimer were studied. The elastic cross section and the cross section for the excitation of low quanta of discrete vibrations were found to be of a similar magnitude for both targets. A dramatic difference was found in the excitation of a vibrational quasicontinuum in the 1–2 eV range with the ejection of very slow electrons (E<0.1 eV), which was about 20× more intense in the dimer. The association of two formic acid molecules to form a dimer thus dramatically increases the power to quasithermalize electrons arriving with energies in the 1–2 eV energy range. Rapid electron-driven intracluster proton transfer is invoked to explain the observation. application/pdf https://folia.unifr.ch/global/documents/300285 https://folia.unifr.ch/documents/300285/files/allan_ecf.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1103/PhysRevLett.98.123201 info:eu-repo/semantics/openAccess License undefined Physical Review Letters. - 2007, vol. 98, no. 12, p. 123201 info:eu-repo/classification/udc/54 Electron collisions with formic acid monomer and dimer http://purl.org/coar/resource_type/c_6501
