LIGHT-ION IRRADIATION IN THE BULK OF AMORPHOUS (PD80SI20)96.5LI3.5 RIBBONS

Irradiation experiment was carried out in the bulk of amorphous (Pd80Si20)96.5Li3.5 by light ions, which are produced by the following nuclear reaction in a nuclear reactor: Li-6 + n --> H-3 + He-4 Structural changes before and after irradiation were determined by X-ray diffraction, small angle X-ray scattering and EXAFS (extended X-ray absorption fine structure) measurements. Scattering amplitudes in the X-ray diffraction and EXAFS decreased after irradiation with much less radiation fluence than by that previously done by the Van de Graaff accelerator. The scattering intensity in small angle region increases with the increase in radiation fluence.
