Fluid mercury and caesium at high temperatures

In the next two sections we review experimental work on the conductivity and magnetic properties of the following materials  

We discuss these materials under the following assumptions. 

In fluids, we have already postulated that quantum interference does not occur. Of course, in liquids no sharp metal-insulator transition can be expected, and therefore we define the transition as occurring when a = amln, the quantity given by equations (50 a, b) of Chapter 1. We therefore believe that it is legitimate to write for the thermopower 

140-200fK1 cm-1. Freyland et al (1974) obtained similar results for caesium, with t0 30011 1 cm-1. All of these results are in fair agreement with our predictions. 

For selenium the value is smaller, about 20I2 1 cm-1 (see Fig. 10.10(b) and also Kao and Cutler 1988). In Section 6 we suggest that this is a consequence of the chain structure of this material.
