We use the method of reduction in the angular variable to construct an infinite-dimensional invariant torus for a linear system of differential-difference equations that depends on an infinite set of constant deviations of arguments of different sign

In the space of bounded number sequences, we establish sufficient conditions for the existence of invariant tori for nonlinear countable systems of difference-differential equations defined on infinite-dimensional tori and containing an infinite set

Grazing incidence nuclear multilayer diffraction of synchrotron radiation from a periodic stack of alternating 56Fe and 57Fe layers was observed. Resonant layer fraction, substrate size, flatness, and surface roughness limits were optimized by previo

We discuss an approach towards understanding the limitations of X-ray or neutron reflectivity methods for the determination of an interfacial density profile. A novel analysis is presented based on an expansion of the reflectivity function in terms o

Polarized neutron specular reflection (PNSR) was used for the study of the magnetization profile of the sandwich Pd/Co(21 A/Pd in a saturating magnetic field prepared by high vacuum vapor deposition on a Au film deposited on a Si(111) and Si(100) sub

Resonant nuclear reflectivity of multilayer structures measured in the specular region as a function of the angle of incidence and Mossbauer velocity (or delay time) contains full depth-selective information on hyperfine interactions. High intensity

The spectral dependence of the reflectivity from thin films of natural Gd and GdTi alloy has been measured. The scattering length of Gd has resonances in the thermal region and consequently its compensation in a wide interval of neutron wavelengths i

We demonstrate that the magnetic state of a thin magnetic film can be probed using polarized neutron reflection even when the magnetization in the film plane is at 90° to the polarization direction of the incident neutron beam. For this special case

The Time-of-Flight Polarized Neutron Spectrometer (SPN-1) is installed at the IBR-2 reactor (JINR, Dubna). The possibility of using this instrument for the reflectometry of thin films is described. Some experiments performed in the reflectometry mode
