Abstract
Measurements of electrical resistivity, rho , and thermopower, S, of solid (above room temperature) and liquid high-purity Eu and Yb are reported. No evidence for the suggested 'transition' in solid Yb at about 300 degrees C is seen in either rho (T) or S(T). Measured values for rho , d rho /dT, and S for these liquid metals at their melting temperatures are, respectively, 241, -0.066, and 6.6 (for EU), and 113.8, -0.023, and -12.2 (for Yb), where the units are mu Omega cm, mu Omega cm degrees C-1, and mu V degrees C-1, respectively. These liquid values are compared with recent calculations based on the t matrix.
