Stability conditions for bound states in antiprotonic atoms

Year: 2025

Type: article

Abstract: We study the stability of bound antiprotons in close proximity to the atomic nucleus. Using experimental data from x-ray spectroscopy measurements of antiprotonic atom transitions, we tune a minimal theoretical framework and estimate parameter ranges where the strong or electromagnetic decay channels govern the stability of the deepest bound states. In this way, we present an overview of the dominant decay mechanism of antiprotonic orbits for a given principle quantum number, to assist future spectroscopic experiments on antiprotonic atoms.
