Spectroscopic characterization of actinide materials

摘要: Advanced spectroscopic techniques provide new and unique tools for unraveling the nature of electronic structure actinide materials. Inelastic neutron scattering experiments, which address temporal aspects lattice magnetic fluctuations, probe electromagnetic multipole interactions coupling between vibrational degrees freedom. Nuclear resonance clearly demonstrates different ground states at low temperature. Photoemission spectroscopy provides information on occupied part density has been used to investigate momentum-resolved topology Fermi surface in a variety compounds. Furthermore, x-ray absorption electron energy-loss have relativistic nature, occupation number, degree localization 5f electrons across series. More recently, element- edge-specific resonant non-resonant inelastic experiments provided opportunity measuring elementary excitations with higher resolution than traditional techniques. Here, we will discuss results from these what they tell us properties selected
