Neutron diffraction experiments were performed on the liquid alloys NaGa, NaGa 3 , KGa 3 and CsGa 3 . The structure factors of KGa 3 and CsGa 3 display prepeaks at small wavenumbers (0.64 and 0.61 Å ‐1 , respectively). This may indicate the existence of extremely large aggregates of atoms in the liquid, which can not be associated with any of the crystal structures known for the solid counterparts of these alloys.
