Persistence of well defined collective excitations in molten metals and binary metallic alloys

The presence of well defined collective excitations in molten potassium is investigated by the concurrent use of neutron-scattering techniques. These allow the separation and proper modeling of coherent and incoherent contributions to the total spectra. The results are discussed together with data p...

More Information
Summary:The presence of well defined collective excitations in molten potassium is investigated by the concurrent use of neutron-scattering techniques. These allow the separation and proper modeling of coherent and incoherent contributions to the total spectra. The results are discussed together with data pertaining to more complex metallic ellements as well as metallic binary mixtures.
