Abstract
Neutron diffraction measurements have been made on liquid Cs-Pb alloys at the Intense Pulsed Neutron Source. Equiatomic CsPb has been shown in previous work to be a Zintl alloy with well-defined Cs4Pb4 structur al units, explaining the anomalously high electrical resistivity and s pecific heat observed in the molten state. These studies have been ext ended to the Cs80Pb20 and Cs25Pb75 compositions and also repeated with the equiatomic composition as a reference. The structure of liquid Cs 25Pb75 resembles that of solid KPb2. Liquid Cs80Pb20 exhibits large co mposition fluctuations.
