A procedure is considered for extracting the energy value of a virtual singlet proton–proton state from experimental data. A preliminary value of Epp in the d + 1H → p + p + n reaction at a deuteron energy of 15.3 MeV is obtained from a comparison of experimental data and simulation results.
Previously, we estimated the neutron flux from the synchrotron of the Konstantinov St. Petersburg Institute of Nuclear Physics, at various moderator configurations near the internal target used to create a neutron flux by the spallation reaction. In this work, we made a successful attempt to transmute Am-241.
Using a method based on mathematical operations with Maxwell’s equations in vector form, it is proved that electromagnetic waves propagating in an arbitrary direction in a bi-gyrotropic medium are always characterized by the collinear orientations of the Poynting vector and the group velocity vector. It is shown that the corresponding Cartesian components of these vectors are proportional to each other, which confirms the collinearity of these vectors. It is found that for all types of electromagnetic waves propagating in an unbounded ferromagnetic medium (which is a special case of a bi-gyrotropic medium), these vectors are always codirected.
Accounting for the effects of local parity nonconservation in a strongly interacting medium is implemented within the framework of the Monte Carlo model. Predictions are obtained for the distributions of the invariant masses of di-muons and di-electrons from the decays of light vector mesons in Pb–Pb collisions at the LHC energy, taking into account the resolution of the detecting systems. The influence of fluctuations of the axial chemical potential is estimated.
The author explains the difference between the areas covered by geostationary lightning detectors manufactured by specialists from different national space agencies. The creation in the near future of a full-fledged geostationary constellation equipped with such detectors is predicted. Promising new tasks are proposed for such a constellation not included in NASA’s list for a single geostationary detector: monitoring dual-use systems, using lightning as a source of electromagnetic waves in studying plasma processes in the ionosphere, and planetary monitoring of mega lightning.
Based on the existing correlation between the deformation energy and the lowest excitation energy, estimates were made of the energies of the (2_{1}^{ + }) states of lanthanide nuclei. The considered systematics of energy relations in the rotational band also made it possible to obtain estimates for the (4_{1}^{ + }) and (6_{1}^{ + }) states of lanthanide nuclei.
