(a) Crystal structure with space group P6/mmm (No. 191) and (b) hole-size distribution of the deuterium occupation sites A2B4, A2B2, AB3 and B4 for LaNi4.5Al0.5 after deuterium absorption, indicated using the ratio of each D–M correlation to the total. The distribution using the ratio to constituent elements is also shown. |
