Observation of the coexistence of crystalline and liquid-like states in krypton-doped argon clusters

Superposition of narrow diffraction peaks and wide bands of the halo type has been observed for large, mixed Ar–Kr clusters ( N = ( 6 – 9 ) ⋅ 10 4 atoms/cluster). Such a superposition shows that a crystalline solution and a phase component with short-range order (liquid-like) coexist. The effect has...

Description
Summary:Superposition of narrow diffraction peaks and wide bands of the halo type has been observed for large, mixed Ar–Kr clusters ( N = ( 6 – 9 ) ⋅ 10 4 atoms/cluster). Such a superposition shows that a crystalline solution and a phase component with short-range order (liquid-like) coexist. The effect has not been previously observed either for atomic macrosystems or for large atomic clusters. The result obtained could indicate nonclassical properties of large argon clusters doped with krypton.
