The dependence of the electric field gradients (EFGs) in the Hf-doped LaNi5-hydrogen system, as a function of hydrogen composition ratio (X), has been investigated in the range 0≤X≤5.7 using the Time Differential Perturbed Angular Correlation (TDPAC) technique. The TDPAC spectrum of LaNi5 was fitted with a single EFG, while two EFGs were needed to fit the LaNi5Hx spectra. The first EFG was similar to the one found in metallic LaNi5 and the second one was interpreted as related to those probe atoms located in the basal plane next to hydrogen interstitial sites located in the same plane. The relative fraction of the probe atoms experiencing these EFGs is dependent on the relative occupation of hydrogen in these sites.
