Solid equiatomic K—Cs alloys have been investigated by X.ray diffraction throughout the temperature range 300—100 K. The results indicate that a phase
Another ordered crystal is observed phase belowtransformation 120K. There isinnothis change of lattice symmetry but the unit cell constants shrink to the values:a=9.1l(1)Aandc= 10.86(2)A(at 110K). The transformation can be ascribed to a rearrangement of the electronic structure of Cs.
