Positron annihilation in H collision above the Positronium formation threshold
S. L. Yakovlev, C-. Y. Hu
A long-standing problem to account for the electron-positron annihilation in positron Hydrogen scattering above the Positronium formation threshold has been resolved by the use of…
direct annihilation above the positronium formation threshold
C-. Y. Hu, D. Caballero, A. Forrester +1
A long-standing problem with the solution of the Schrödinger equation has been its inability to account for the electron-positron annihilation in positron hydrogen scattering above…
Multichannel scattering on excited Ps states
Z. Papp, D. Caballero, C-. Y. Hu
Scattering and reaction cross sections of system are calculated for total angular momentum L=0, 1 and 2 and energies between the Ps(n=2)-Ps(n=3) threshold. We solved a…
Resonant-state solution of the Faddeev-Merkuriev integral equations for three-body systems with Coulomb-like potentials
Z. Papp, S. L. Yakovlev, C-. Y. Hu +3
A novel method for calculating resonances in three-body Coulombic systems is presented. The Faddeev-Merkuriev integral equations are solved by applying the Coulomb-Sturmian separab…
