(16) Mathematical methods in quantum mechanics; perturbation
theory in atomic physics; summation of divergent series. We
developed semiclassical methods for calculating the
energies and the widths of bound and exited (especially
Rydberg) states for screened Coulomb potentials, Stark and
Zeeman effects, helium-like ions, and two-centre-Coulomb
problem. We have been investigated strong-field Stark effect
in a hydrogen atom. I am involved in mathematical aspects of
the work. I have contributed in developing special summation
procedures and in generalization of dimensional expansions
on few-particle systems. Now we are looking for asymptotics
of large orders of coefficients in 1/N-expansion.
