Fm3m (NO.225),晶胞中各原子坐标为:+8Mg(0.25, 0.25, 0.25)；+4Fe(0, 0, 0)；+24H(x, 0, 0),x为(0~0.240)[24].由于实验未检测出Mg2FeH6晶胞结构(Mg8Fe4H24)中H原子的位置,为此,选择实验值附近不同的晶格常数和不同的x值进行了一系列的计算,发现Mg2FeH6晶体的平衡晶格常数 (6.401?)与实验值 (6.443?[24],6.444 ?[5],6.442 ?[25],6.429 ?[26])符合得较好,同时对应x=0.240时,Mg2FeH6晶胞的总能量(?11 679.253 5 eV)为最低值.由于总能量越低,对应晶胞结构越稳定,为此确定Mg2FeH6晶胞结构中H原子的坐标为(0.240, 0, 0). 2.4 H2在Mg(0001)表面的吸附 为探讨球磨Mg是否有助H2被Mg表面吸......
