Abstract We study the unexpected distorted wave effects of the 1b3g orbital in ethylene using a high resolution binary (e, 2e) electron momentum spectrometer, at an impact energy of 800eV plus the binding energy (8-22eV) with symmetric non-coplanar kinematics. The experimental momentum profile of the 1b3g orbital is obtained and compared with the data previously measured at impact energy of 1200 eV plus the binding energy. Also, the experimental momentum profiles of the 1b3g orbital are compared with the theoretical momentum distributions calculated by using Hartree-Fock and density functional theory methods. The experimental momentum profiles of the 1b3g orbital of ethylene at different impact energies show that the cross section of the orbital below the momentum p～1 a.u. is higher for lower impact energy.
