The Mossbauer spectra of 237Np in NpH2+x(x = 0.1, 0.3 and 0.5) consist of several absorption lines which are attributed to Np inequivalent sites corresponding to different numbers of octahedral hydrogen neighbours. The relative intensities of the various lines do not correspond to a random distribution of the hydrogen ions. A model which takes into account first nearest neighbour interactions among octahedral hydrogen ions can reproduce the experimental spectra.
