Hyperfine structure S state of muonic helium atom

Aznabayev, D.T.; Bekbaev, A.K.; Korobov, V.I. (2021)

In this work the nonrelativistic ionization energies 3He2+µ −e − and 4He2+µ −e − of helium-muonic atoms are calculated for S states.The estimates are based on the variational principle of exponential expansion. ...

Oscillation and spectral properties of some classes of higher order differential operators and weighted nth order differential inequalities

Kalybay, Aigerim; Oinarov, Ryskul; Sultanaev, Yaudat (Electronic Journal of Qualitative Theory of Differential Equations, 2021)

In this paper, we obtain strong oscillation and non-oscillation conditions for a class of higher order differential equations in dependence on an integral behavior of its coefficients in a neighborhood of infinity. ...
