Outline of Final Research Achievements |
The structural features of amorphous alloys and germanate glasses were investigated using a reverse Monte Carlo simulation with the combinational use of anomalous X-ray scattering and neutron diffraction. Further, pressure dependence of the structural functions for the amorphous germanate sample were obtained by using the neutron diffraction with high Q region.
