Description:
<jats:title>Abstract</jats:title><jats:p>Inelastic neutron scattering measurements have been performed on polycrystalline samples of the cerium hydrides CeH<jats:sub>1.98</jats:sub>and CeH<jats:sub>2.72</jats:sub>at 70 °C in order to study their lattice dynamics. For the data analysis the spectrometer resolution has been carefully taken into account. A qualitative interpretation of the results clearly shows the importance of hydrogen‐hydrogen interactions. A diffusive motion of hydrogen could not be observed for both samples.</jats:p>
