چکیده انگلیسی
Despite of the impressive range of experimental information on the physical properties of plutonium almost nothing is known on the magnetic dynamics in all plutonium phases. The plausible magnetic spectral response in fcc Pu has been calculated on the basis of the single-ion Kondo model and comparison with a model system CeNi, which is a good analogue of fcc Pu regarding the characteristic Kondo energy scale and partial delocalization of the f-electrons. A broad peak centered at about 40 meV dominates in the spectrum at low temperatures. The most interesting energy transfer range for the inelastic neutron scattering experiments measurements on fcc Pu is 20-150 meV. Magnetic excitations in itinerant systems like Cr and α-Pu are discussed.
