Braun, M. Ruf, M.-W. Hotop, Hartmut Allan, Michael 2006 In high resolution electron attachment to SF₆, cusp structure due to interchannel coupling has been observed in the cross-section for SF₅⁻ formation at the thresholds for vibrational excitation of the SF₆(<i>v</i>₁) mode up to <i>v</i>₁ = 10. It is superimposed on the broad band peaking around 0.55 eV which has been previously attributed to attachment into a repulsive potential surface and subsequent direct dissociation. The newly observed vibrational structure as well as electron energy loss spectra (which exhibit strong excitation of the <i>v</i>₁ mode up to high quantum numbers) indicate, however, that both the channel yielding the long-lived SF₆⁻ anions and the dissociative SF₅⁻ + F channel have a common primary attachment process, mediated by the same SF₆⁻ scattering state and strongly coupled to the process of vibrational excitation. application/pdf https://folia.unifr.ch/global/documents/299968 https://folia.unifr.ch/documents/299968/files/allan_lee.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1016/j.cplett.2005.12.005 info:eu-repo/semantics/openAccess License undefined Chemical Physics Letters. - 2006, vol. 419, no. 4-6, p. 517-522 info:eu-repo/classification/udc/53 Low-energy electron attachment to SF₆ molecules: Vibrational structure in the cross-section for SF₆⁻ formation up to 1 eV http://purl.org/coar/resource_type/c_6501
