The phonon spectra and vibrational thermodynamical characteristics of the Pd-H superlattices are investigated. Results of our calculations give a possibility to agree the data of neutronographic and calorimetric experiments and explain for the such systems the atomic mean square amplitudes and correlations between ones.
