Analyses of the local structure around La and Ni atoms in amorphous LaNi<SUB>5.0</SUB> films have been performed using the extended X-ray absorption fine structure (EXAFS), and the effect of the structure on the difference of hydrogen absorption characteristics between the amorphous and crystalline LaNi<SUB>5.0</SUB> has been elucidated. The lengthening of interatomic distances for the Ni–Ni and La–Ni pairs, respectively, was observed for the amorphous samples in comparison with the crystalline ones. A part of the hydrogen sites existed in the crystalline LaNi<SUB>5.0</SUB> was distorted in the amorphous one. Since the hydrogen atoms appear to be difficult to enter these sites distorted, the hydrogen content in the amorphous LaNi<SUB>5</SUB> is smaller than that in the crystalline one.
