Electron-impact vibrational excitation of furan

We report measurements of differential cross sections for the vibrational excitation of furan (C${}_{4}$H${}_{4}$O), obtaining results for nine features spanning the electron energy loss range from 0 to 0.8 eV, at electron-impact energies of 5, 6, 7.5, 10, and 15 eV and for scattering angles ranging from 10${}^{\mathrm{o}}$ to 130${}^{\mathrm{o}}$. The normalization of the differential cross sections was done using elastic differential cross sections for furan determined earlier by our group [Khakoo et al., Phys. Rev A 81, 062716 (2010)].
