μSR-study of reactivity of substituent ions and point-like defects in quartz monocrystals

SR-method has been used for studying reactions of muonium as an analogue of a light hydrogen isotope with impurity atoms and point-like defects. The relaxation rate of muonium polarization _Mu was measured for 11 samples with different concentrations of impurity atoms and defects. The rate constants of reactions of muonium with Fe, Al, Li, Ba, Cu, Mn, Ti and Pb atoms in quartz were defined.     

Exact solutions of vacuum Brans-Dicke equations

Vacuum Stäckel type (2.1) spaces are classified in Brans-Dicke theory for the case when the scalar field depends on all the variables.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 1, pp. 86–90, January, 1992.     

Isotropic Steklov-conformal metrics of plane-conformal spaces

An explicit form is found for metrics that allow integration of geodesic equations for massless particles in plane-conformal spaces by complete separation of the variables in the Hamilton-Jacobi equations.

Stueckel spaces of the electrovacuum with two-parameter Abelian group of motions. Formulation of the problem and sets of the type (2.1)

The problem of finding all spaces of the electrovacuum with the additional condition that thh variables in the Hamilton-Jacobi equation be completely separable is formulated. All spaces admitting separation of variables of the type (2.1) are found.
