Absolute elastic cross sections for electron-propane (C{sub 3}H{sub 8}) collisions have been measured using incident kinetic energies of 2, 3, 4, 5, 6, 7.5, 8.5, 10, 15, 20, 40, and 100 eV and recorded over scattering angular range of 10{degrees} to 130{degrees}. These cross-sections have been integrated by employing a nonlinear phase shift fitting procedure. Angular distributions have been found to correspond at least qualitatively to a scattering formulation using only local potentials and also to a multi channel Schwinger variational calculation. Experiments on vibrationally inelastic scattering reveal the existence of a shape resonance with a peak at 7.5 eV characteristic of trapping by C-H antibonding valence orbitals.
