Scattering in and systems: mass dependent and mass independent features of cross sections above the degenerated thresholds
V. A. Gradusov, S. L. Yakovlev
Ab initio calculation of low energy scattering of electrons (muons) off hydrogen (muonic hydrogen) are performed on the basis of Faddeev-Merkuriev (FM) equations. The explicit cont…
The Gailitis-Damburg oscillations in the three-body system
V. A. Gradusov, S. L. Yakovlev
We study the near threshold behavior of cross sections of low-energy antiproton scattering off the ground and excited states of positronium with zero total orbital momentum .…
On scattering problem off the potential, decreasing as inverse square of distance
V. A. Gradusov, S. L. Yakovlev
A solution of the scattering problem is obtained for the Schrödinger equation with the potential of induced dipole interaction, which decreases as the inverse square of the distanc…
On Green's functions for Hamiltonians with potentials possessing singularity at the origin: application to the zero-range potential formalism
Sergey L. Yakovlev, Vitaliy A. Gradusov
We evaluate the short-range asymptotic behavior of Green's function for a Hamiltonian when its potential energy part has an inverse power singularity at the origin. The analyticall…
Zero range potential for particles interacting via Coulomb potential: application to electron positron annihilation
S. L. Yakovlev, V. A. Gradusov
The zero range potential is constructed for a system of two particles interacting via the Coulomb potential. The singular part of the asymptote of the wave function at the origin w…
