Electrical resistivity due to dissolved H in Pd

Abstract
The incremental resistivity of hydrogen in alpha -Pd has been measured in the temperature range 250-350 K at hydrogen concentrations below 1 at.%. The reliability of the values obtained by electrochemical doping with H is discussed. The strong temperature dependence of the incremental resistivity is due to the electron scattering on optical phonons having a low excitation energy in dilute Pd-H.
