Two-Dimensional Low-Energy Scattering of a Quantum Particle
Publications, 13 January 2020
We are glad to bring to your attention a new preprint «Two-Dimensional Low-Energy Scattering of a Quantum Particle in the Combined Field of the Coulomb and Power Potentials» P4-2019-53 published by the JINR Publishing Department. The author of the work is Pupyshev V. V.
We study the two-dimensional scattering of a quantum particle by the force center acting on it through a superposition of the Coulomb and power potential V0 r–β with the exponent β ∈ (1,2). For this scattering, we found explicit low-energy asymptotics of all partial phase-shifts and amplitudes.
