Implication

Theoretical study reveals scattering cross sections in antiproton-positronium collisions up to high excited states, highlighting scalable pathways for cold anti-atomic physics applications.

Key Points

To calculate scattering cross sections and analyze collision dynamics, such as breakup and charge transfer, in the three-body antiproton-positronium system.
Simulated collision dynamics using both quantum convergent close coupling and classical trajectory methods.
Evaluated scattering cross sections across diverse positronium kinetic energies and excited states up to principal quantum number n_Ps ≤ 6.
Derived comprehensive cross sections for all primary scattering processes, notably charge transfer and atomic breakup.
Demonstrated that direct quantum-classical comparison provides a systematic method to accurately extrapolate cross sections to arbitrarily high excitation states (n_Ps > 6).
