The two-stage two-proton virtual nuclear decay theory and superfluid atomic nucleus model are used to investigate the total and partial widths, and the angular distributions of the emitted protons, for the two-proton diagonal virtual decay of the gro

The approach proposed by A.B. Migdal for describing the virtual singlet diproton state is used to show the effect diproton decay channel has on the width and the angular distribution of emitted protons in the two-proton decay of a parent 45Fe nucleus

On the basis of the theory of diagonal two-proton two-step virtual decays of spherical nuclei that was developed earlier and the superfluid model of the nucleus, the total and partial widths for the two-proton decay of the 45Fe parent nucleus in the

A general theory of many-body diagonal and nondiagonal one-proton decays of spherical and deformed nuclei is developed on the basis of an approach not employing R-matrix theory in describing deep-subbarrier alpha and one-proton decays of nuclei but r

Using the results from the many-particle theory of deep subbarrier single-proton decays (SPDs) of nuclei, which is based on integral formulas for SPD widths, a general theory of successive two-stage two-proton decays (TSTPDs) from the ground and exci

A formalism for describing two-step two-proton decays of nuclei is developed on the basis of the multiparticle theory of deep-subbarrier one-proton decays of nuclei that employs integral expression for the decay widths in question. This formalism rel

The time dependences of the populations of radical-pair spin states and transition amplitudes between them have been calculated for constant and pulsed magnetic fields, with allowance for hyperfine interaction. The above-mentioned characteristics hav

A method for calculating the widths of two-proton decay of nuclei with regard to its deep subbarrier character is proposed. The structure and coupling of the channels of facilitated two-proton decay of spherical nuclei are considered for the diproton

A phenomenological theory is developed that describes the effect of a magnetic field on the defect reactions in a solid. The theory is based on a concept regarding the lattice magnetism according to which a defect induces a magnetoactive (magnon) bra

The time dependences for a population of radical pair spin states and the amplitudes of the transitions between them are calculated for magnetic fields of complex configuration. The abovementioned values are derived directly from the solution to the
