Electron collisions with furan

The authors report integral, differential and momentum transfer cross sections for elastic scattering of low-energy electrons by C4H4O (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. (C) 2007 American Institute of Physics.
