Neutron diffraction study of the structure of liquid cerium and praseodymium

Abstract
The structure factors of liquid Cerium and Praseodymium have been determined at 1 100 C by neutron diffraction. For theoretical and experimental reasons paramagnetic scattering has been assumed to be identical in both liquid and solid states. The pair correlation functions, neighbour distances and coordination number were then obtained by Fourier transform. The structure factor S(k) exhibits an anomalous behaviour compared with simple metallic ions
