title: Electron collisions with furan.
abstract: The authors report integral, differential and momentum transfer cross sections for elastic scattering of low-energy electrons by C(4)H(4)O (furan) molecules. Their calculations employed the Schwinger multichannel method with pseudopotentials and were performed in the static-exchange and in the static-exchange plus polarization approximations. The authors found two shape resonances located around 2.1 and 4.2 eV that belong to the B(1) and A(2) symmetries of the C(2v) group, respectively. The authors' results are consistent with recent measurements of vertical electron attachment energies.
