†7 | The residual electrical resistances of pure specimens of Ag, Al, Au, Cu, Fe, Mo, Ni, Ti, and W, at temperatures of 20 K, were changed by high-energy (0.5 MeV to 1.4 MeV) electron bombardment. The resistivity change per unit electron flux is plotted as a function of average electron energy for Ag, Al, Cu, Fe, and Ni. |
