Figure 4
Neutron diffraction patterns and Rietveld refinements for LaNi4.5Al0.5 (a) before, (b)–(i) during (10 s intervals) and (j) after deuterium absorption at room temperature. Rietveld refinement results: observed (circles), calculated (line) and residual (line below the vertical bars) diffraction profiles. Bragg reflection positions are from LaNi4.60Al0.40 and LaNi4.64Al0.36D4.99. |
