摘要：

The intermediate phase of the intermetallic alloy CsPb is shown to be a plastic crystal characterized by jump reorientations of Cs4Pb4 structural units. The wave-vector variation of elastic and quasielastic intensities is well reproduced by a simple model of independent structural units jumping between the four orientations observed in the crystal at room temperature. This represents the first observation of a plastic-crystal phase in a metal alloy.
