摘要：

The first-order difference method of neutron diffraction is applied to molten GeSe2 at 784 +/- 3-degrees-C. The results show that Ge correlations contribute to the first sharp diffraction peak of the total structure factor, give a nearest-neighbour distance rBAR(GeSe) = 2.40 +/- 0.02 angstrom and give an average coordination number of 3.7 +/- 0.2 selenium atoms around a germanium atom.
