    Abstract

    Neutron diffraction measurements on liquid KTl were performed using Tl-205 isotope substitution. The measurement gives evidence for the occurrence of Tl-clusters with an average mutual distance of 0.96 nm. The structure in liquid KTl is compared with the crystal structures of KTl and K8Tl11, where resp. Tl-6 and Tl-11 clusters occur. To extend the search for analogies in the structure of liquid and solid alloys, we also measured liquid K8Tl11, K8Tl10Zn, K10Tl10Pd, and K18Tl20Au3, they all exhibit interesting crystal structures with large clusters (Tl-11, Tl10Zn, Tl10Pd and Tl9Au2). Indeed, some similarities are found between the structures in these liquid alloys and their solid counterparts.
