Abstract:

A STUDY WAS MADE TO INVESTIGATE RADIATION EFFECTS IN THIN METALLIC FILS PREPARED BY THE VACUUM EVAPORATION PROCESS. opper and gold films were deposited in vacuum by the thermal evaporation process on soft gass and stainless steel sbtrates and irradiated at Brookhaven NATIONAL Laboratory at room temperature by Cobalt 60 gamma ays. The electrical resistivity was measured and X-AY DIFFRACTION PATTERNS WERE OBTAINED BEFORE AND AFTER IRRADIATION OF THE SAMPLES ON THE GLSS SUBSTRATES. Broadening of the X-ray diffraction patterns occurred upon irradiation of the amples on glass, but not on metal substrates. Resistivity changes were observed, but were not correlated with ths line broadening. Author
