CoO(100) has been characterized by AES, XPS, and LEED subsequent to th
e measurement of its Fuchs-Kliewer phonon spectrum by high resolution
electron energy loss spectroscopy. The fundamental phonon frequency is
observed at -68.9 meV and multiple losses are found to higher losses
energy following a Poisson intensity distribution. Phonon intensity va
riation with HREELS primary beam energy is also measured and indicates
intrinsic dipole loss behavior.
