We present results for the isovector axial, induced pseudoscalar, electric, and magnetic form factors of the nucleon. The calculations were done using 2 + 1 + 1-flavor HISQ ensembles generated by the MILC collaboration with lattice spacings a ≈ 0.12, 0.09, 0.06 fm and pion masses Mπ ≈ 310, 220, 130 MeV. Excited-states contamination is controlled by using four-state fits to two-point correlators and by comparing two-versus three-states in three-point correlators. The Q2 behavior is analyzed using the model independent z-expansion and the dipole ansatz. Final results for the charge radii and magnetic moment are obtained using a simultaneous fit in Mπ, lattice spacing a and finite volume.

The paper is dedicated to the consideration of the chemical mesoscopics notions application for the explanation of polymeric materials modification mechanism by the metal carbon mesoscopic composites. The main peculiarities of these nanosized particles are following: a) the presence of unpaired electrons on the carbon cover; b) the structure of carbon cover consists from poly acetylene and carbine fragments; c) the atomic magnetic moment of inner metal is equaled to more than 1,3 μB. The creation of reactive mesoscopic materials with regulated magnetic characteristics which can find the application as modifiers of materials properties is very topical. The present investigation has fundamental character. It’s based on the ideas concerning to the metal carbon mesocomposites reactivity depending on the medium and conditions influence because of the possible changes of the phase coherency and quantization of negative charges.

The electronic structure of amorphous and crystalline Fe100–xBx alloys for 14≤x≤19.5 has been studied by x-ray photoelectron spectroscopy and calculated in terms of the modified coherent potential approximation. Exchange splitting measurements of 3s-spectra were used to estimate the atomic magnetic moment of the Fe atom in Fe-B amorphous and crystalline alloys. These results agree qualitatively with saturation magnetization measurements including the deviation from the Slater-Pauling curve. This deviation according to our calculations is the result of the specific charge transfer of s, p and d electrons at about 15.5 at % B. The calculation in ternary alloy approach shows a stable ferromagnetic state of Fe atoms for the studied alloy concentrations.
