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…

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…

Multichannel Scattering Problem with Non-trivial Asymptotic Non-adiabatic Coupling

S L Yakovlev, E A Yarevsky, N Elander +1

The multichannel scattering problem in an adiabatic representation is considered. The non-adiabatic coupling matrix is assumed to have a non-trivial constant asymptotic behavior at…

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…
