| Abstract: | The La-based alloy deuteride LaNi_(4.25)Al_(0.75)D_(1.6) was measured by neutron powder diffraction to investigate the occupying locations of deuterium. The neutron diffraction data were analysed using FULLPROF program. The crystal structure parameters, the atomic occupying locations and occupying numbers of deuterium were obtained after calculation by the program. |

| Keywords: | La-based alloy deuteride Atomic occupying locations Occupying numbers |
