Journal of physics. Condensed matter : an Institute of Physics journal

Demmel F, Fraile A, Szubrin D, Pilgrim WC, Morkel C.
PMID: 26465204
J Phys Condens Matter. 2015 Nov 18;27(45):455102. doi: 10.1088/0953-8984/27/45/455102. Epub 2015 Oct 14.

The temperature dependence of the dynamic structure factor at next-neighbour distances has been investigated for liquid aluminium. This correlation function is a sensitive parameter for changes in the local environment and its Fourier transform was measured in a coherent...
