There may be some confusion here as to the dielectric constant of a conductor, but " if a material with a high dielectric constant is placed in an electric field, the magnitude of that field will be measurably reduced within the volume of the dielectric " ( see main page: Dielectric constant ), and since the electric field is zero in an ideal conductor, then in this context the dielectric constant of a conductor is infinite.

X-ray photoelectron spectroscopy ( XPS ) is a quantitative spectroscopic technique that measures the elemental composition, empirical formula, chemical state and electronic state of the elements that exist within a material.

This technique is complementary to fluorescence spectroscopy, in that fluorescence deals with transitions from the excited state to the ground state, while absorption measures transitions from the ground state to the excited state.

Within transmission EELS, the technique is further subdivided into valence EELS ( which measures plasmons and interband transitions ) and inner-shell ionization EELS ( which provides much the same information as x-ray absorption spectroscopy, but from much smaller volumes of material ).
