Valence Shell Ionization Spectra of Propane by (e, 2e) Spectroscopy

The measurements of the valence shell ionisation energy spectra(6-32eV)for propane(C_(3)H_(8))by high resolution(ΔE=0.9eV andΔp=0.1 a.u.)(e,2e)spectrometer at impact energy of 1200eV plus binding energy and symmetric noncoplanar kinematics are reported.The spectrum is consistent with a single particle picture of ionization from each of the seven outer-valence orbitals and the three inner-valence orbitals.The ionization energies are in agreement with published photoelectron spectroscopy data.
