The specific electrical conductivities of electron beam zone refined tantalum‐molybdenum alloy single crystals were measured at 273, 77, and 4.2°K. It was assumed that the Fermi surface of the alloys is an order of magnitude less than that corresponding to a Fermi sphere and the total scattering cross section behaves like 2π (√2 Λ F ) 2 , where Λ F is the wavelength of electrons at the Fermi surface. Under these assumptions, the calculated electrical conductivities showed good agreement with the observed conductivities at 4.2°K for tantalum rich alloys. The divergence between calculated and observed conductivities in molybdenum rich alloys is attributed to the contribution of holes to the conductivity.
