Abstract

The binding energy and the spherically averaged momentum distributions of orbital 1a" for butanone have been investigated by high resolution electron momentum spectroscopy (ΔE = 1.15 eV, Δp = 0.1a.u.). The impact energy was 1200 eV plus binding energy (i.e. 1206-1242 eV) and symmetric non-coplanar kinematics was employed. The experimental binding energy spectra have been compared with published photoelectron spectra. The momentum profile of 1a" orbital has been compared on a quantitative basis with theoretical calculations using Hartree-Fock method and Density Functional Theory. The position density and momentum density for la" orbital are presented.
