The radial distribution function of hydrogenated metallic glass Ni24.3Zr75.7H0.65 was deter-mined with X-ray scattering technique to investigate the influence of hydrogcnation on the structure of metallic glass Ni24.3Zr75.7 and the local surroundings of hydrogen atoms in the struc-ture of metallic glass Ni24.3Zr75.7H0.65.
