Abstract
The structure of the zeta-phase in the Pu-U system has been determined by neutron powder diffraction. The phase crystallizes in space group R(3) over barm$ with 58 atoms in the primitive unit cell and 10 atoms in the asymmetric unit. The structure is characterized by many short b onds and fits the general pattern of the light actinides. Thermal expa nsion and elastic data were obtained from the diffraction experiments.
