Parity nonconservation effect in the resonance elastic electron scattering on heavy He-like ions
We investigate the parity nonconservation effect in the elastic scattering of
polarized electrons on heavy He-like ions, being initially in the ground state.
The enhancement of the parity violation is achieved by tuning the energy of the
incident electron in resonance with quasidegenerate doubly-excited states of
the corresponding Li-like ion. We consider two possible scenarios. In the first
one we assume that the polarization of the scattered electron is measured,
while in the second one it is not detected.Comment: 13 pages, 3 figures, 2 table
Parity nonconservation effect in the dielectronic recombination of polarized electrons with heavy He-like ions
We investigate the parity nonconservation (PNC) effect in the dielectronic
recombination (DR) of a polarized electron with a heavy He-like ion into
doubly-excited and states of Li-like ion. We determine the
nuclear charge number for which these opposite-parity levels are near to
cross and, therefore, the PNC effect will be significantly enhanced.
Calculations are performed for quantum numbers and .Comment: 12 pages, 1 figur
Calculations of QED effects with the Dirac Green function
Modern spectroscopic experiments in few-electron atoms reached the level of
precision at which an accurate description of quantum electrodynamics (QED)
effects is mandatory. In many cases, theoretical treatment of QED effects has
to be performed without any expansion in the nuclear binding strength parameter
(where is the nuclear charge number and is the
fine-structure constant). Such calculations involve multiple summations over
the whole spectrum of the Dirac equation in the presence of the binding nuclear
field, which can be evaluated in terms of the Dirac Green function. In this
paper we describe the technique of numerical calculations of QED corrections
with the Dirac Green function, developed in numerous investigations during the
last two decades

Parity violation in the resonance elastic electron scattering on He-like uranium
Synopsis Parity violation on the cross section of the resonance elastic electron scattering by He-like uranium ion is studied. It is assumed that the incident electron is polarized and tuned in resonance with one of the close-lying opposite-parity states
Backward scattering of low-energy antiprotons by highly charged and neutral uranium: Coulomb glory
Collisions of antiprotons with He-, Ne-, Ni-like, bare, and neutral uranium
are studied theoretically for scattering angles close to 180 and
antiproton energies with the interval 100 eV -- 10 keV. We investigate the
Coulomb glory effect which is caused by a screening of the Coulomb potential of
the nucleus and results in a prominent maximum of the differential cross
section in the backward direction at some energies of the incident particle. We
found that for larger numbers of electrons in the ion the effect becomes more
pronounced and shifts to higher energies of the antiproton. On the other hand,
a maximum of the differential cross section in the backward direction can also
be found in the scattering of antiprotons on a bare uranium nucleus. The latter
case can be regarded as a manifestation of the screening property of the
vacuum-polarization potential in non-relativistic collisions of heavy
particles.Comment: 14 pages, 5 figure

Thermodynamic properties, namely standard molar enthalpy of formation (ΞHfΒ°298), standard molar entropy (SΒ°298), and temperature dependence of heat capacity (Π‘Ρ(Π’)) of crystalline metal perrhenates, were assessed by the semi-empirical methods. In this work, ΞHfΒ°298, SΒ°298 and coefficients a, b and c for Cp = Π° + 0.001ΓbΓT + 105ΓcΓTΒ β2equation were calculated using several methods and averaged. These thermodynamic properties were calculated for the following perrhenates metals: Li, N, K, Rb, Cs, Cu, Ba, Fe, Ca, Cd, Co, Mg, Mn, Pb, Sr, Zn, Al, CrΠΈ Fe. The calculated values of the thermodynamic properties were in good accordance with the known literature data. New data were applied to the thermodynamic simulation of rhenium-containing sample pretreatment processes for the chemical analysis. The thermodynamic simulation of the sintering sample with the magnesium oxide with/without oxidizing agents was carried out using HSC 6.1 software with new data about the perrhenates. According to the calculated results, the addition of the oxidizing agent (NaNO3 or K2S2O7) to the magnesium oxide was needed and its presence ensured the rhenium transition into the solution without losses. In this case, rhenium was present at the temperature of the sintering predominantly as NaReO4c or KReO4c. Calculation results and estimation of perrhenates thermodynamic properties could be used for the thermodynamic simulation of different processes as well as in analytical chemistry and in metallurgy.Keywords: perrhenates, thermodynamic properties, thermodynamic simulation, sintering, oxidizing agent, rhenium(Russian)Β DOI: http://dx.doi.org/10.15826/analitika.2019.23.4.015Β O.V.

Theoretical and experimental studies were carried out for the first time in order to determine the mechanism of co-precipitation of arsenic and antimony during their separation from the macro-quantities of iron and chromium in the form of Na3FeF6 and Na3CrF6 sediments. It was found that the application of Dubinin-Radushkevich adsorption isotherm gives the most accurate description of the process. The average free energy of adsorption for As and Sb is 9.6 and 9.7 kJ/mol respectively. Co-precipitation of analytes in the micropores of precipitates occurred as a result of the chemical (ion-exchange) reaction. The possibility of inhibiting this process by introducing a different amount of complexing agent (hydrofluoric acid) was studied. The addition of HF led to the formation of more coarse crystalline precipitates with lower specific surface area and porosity. For the accurate ICP-AES determination of analytes (As, Sb) the molar ratio of precipitating agent / complexing agent (NaF / HF) β 1 should be strictly observed. According to the developed procedure, state standard samples of steels and nickel-based precision alloys were prepared for ICP-AES determination of As and Sb contents. The difference between the found and certified content of analytes did not exceed the permitted deviations given in the corresponding Russian state standards. The ICP-AES method of simultaneous determination of As and Sb contents after their preliminary separation from the main components is recommended for the analysis of materials with high content of Fe and Cr.Keywords: sorption, co-precipitation, determination of arsenic and antimony, inductively coupled plasma atomic emission spectroscopy (ICP-AES), adsorption isotherms, fluorides, matrix componentsDOI: http://dx.doi.org/10.15826/analitika.2017.21.3.001Β A.V.
