Abstract

A many-band model of conductivity is stated in terms of which it is shown qualitatively and quantitatively that interference scattering of conduction electrons may be the main reason for the negative temperature coefficient of resistance in actinide alloys at high temperatures (T > ΘD). The temperature run of the resistivity in such alloys is completely determined by the balance between coherent and incoherent contributions to electron-impurity-phonon scattering. The model is used to analyze the concentration and temperature dependences of the plutonium and americium alloy resistivity.
