We present absolute measurements of differential elastic electron
scattering cross sections from benzene (C6H6) and
hexafluorobenzene (C6F6). The measurements have been performed
in our two laboratories on different crossed-beam apparatuses for
scattering angles between 10° and 130°: C6H6
at the Australian National University in the energy range from 1.1 to
40 eV, and C6F6 at Sophia University from 1.5 to 100 eV. The
cross sections for both molecules, which are characterized by strong
forward-angle scattering and large-angle oscillations, are favourably
compared with recent theoretical calculations.
Absolute differential cross sections for elastic scattering of electrons from sulfur hexafluoride (SF 6 ) have been measured at 11 incident energies between 2.7 and 75 eV and for scattering angles between 10 • and 130 • . The magnetic angle-changing device of Read and coworkers has been used to extend these measurements to backward angles (130 • -180 • ) for incident energies below 15 eV. The measurements reveal some substantial differences with several previous determinations and a reasonably good level of agreement with a recent close-coupling calculation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
