Abstract A temporary negative ion resonance at 8.9eV in C2F6 has been clearly identified using angle-resolved electron energy loss spectroscopy at 2.5keV impact energy, and can be attributed to electron capture into 12alu, 12a1g, 22a2g, and 12eg virtual molecular orbitals. The corresponding absolute generalized oscillator strength profile is found to have a shape characteristic of non-dipole interaction with the maximum K ~ 0.8a.u. of momentum transfer.
