Liquid-liquid equilibrium. We have used the classical Molecular Dynamics method to calculate the structure factor S(Q) of liquid Li and we compare this quantity with that measured by neutron scattering. It is well known that the structure factor a(q) of monatomic liquids at temperatures close to their triple points can be crudely modelled by hard-sphere structure factors a,,(qtprovided the packing fraction of the hard spheres lies in the range 0.45-0.47 (Ashcroft and Lekner 1966). Results of measurements of the liquid structure factor S(k) of 3 He are presented. The dynamical structure factor of supercooled Na0:5Li0:5PO3 (Tg ‹515 K, Tm ‹749 K) has been obtained by time-of-flight neutron scattering between room temperature and 773 K, just above the melting temperature. Journal of Low Temperature Physics $${\displaystyle \mathbf {q} =\mathbf {k_{s}} -\mathbf {k_{o}} }$$, where $${\displaystyle \mathbf {k_{s}} }$$ and $${\displaystyle \mathbf {k_{o}} }$$ ( $${\displaystyle |\mathbf {k_{s}} |=|\mathbf {k_{0}} |=2\pi /\lambda }$$) are the scattered and incident beam wavevectors, and $${\displaystyle \theta }$$ is the angle between them.

It has a role as an amphiprotic solvent, a fuel, a human metabolite, an Escherichia coli metabolite, a mouse metabolite and a Mycoplasma genitalium metabolite. The data were taken at temperatures near0.4 K over the momentum transfer range0.15 Å−1
