Hoszowska, Joanna Cao, Wei Simon, M. 2010-04-12 We present measurements of the resonant inelastic x-ray scattering (RIXS) spectra of the CH3I molecule in the hard-x-ray region near the iodine L2 and L3 absorption edges. We show that dispersive RIXS spectral features that were recognized as a fingerprint of dissociative molecular states can be interpreted in terms of ultrashort natural lifetime of ∼200 attoseconds in the case of the iodine L-shell core-hole. Our results demonstrate the capacity of the RIXS technique to reveal subtle dynamical effects in molecules with sensitivity to nuclear rearrangement on a subfemtosecond time scale. application/pdf https://folia.unifr.ch/global/documents/301812 https://folia.unifr.ch/documents/301812/files/hos_rix.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1063/1.3575514 info:eu-repo/semantics/openAccess License undefined The Journal of Chemical Physics. - 2011, vol. 134, no. 14, p. 144308 info:eu-repo/classification/udc/53 Resonant inelastic x-ray scattering at the limit of subfemtosecond natural lifetime http://purl.org/coar/resource_type/c_6501
