Abstract
The structural properties of LaNi4CoD6.11 and LaNi3.55Mn0.4Al0.3Co0.75 D5.57 deuterides have been investigated by means of powder neutron dif fraction analysis. The data analysis of LaNi4CoD6.11 deuteride has bee n performed using a modified Rietveld procedure in order to take into account the anisotropic broadening of the observed diffraction lines. Distribution of Mn, Al and Co substituting atoms on the nickel sublatt ice and occupancy rate determination of the occupied deuterium sites h ave been achieved and are compared with those of other single substitu ted compounds.
