High precision X-ray spectroscopy of kaonic neon

Francesco Sgaramella, D. Sirghi, K. Toho, F. Clozza et autres

The high-precision kaonic neon X-ray transitions measurement performed by the SIDDHARTA-2 collaboration at the DAΦNE collider is reported. Both the X-ray energies and yields for high-n transitions were measured, demonstrating the feasibility of sub-eV X-ray spectroscopy for kaonic atoms using low-Z gaseous …

SIDDHARTA-2 apparatus for kaonic atoms research on the DAΦNE collider

Florin Catalin Sirghi, M. Iliescu, L. Abbene, C. Amsler et autres

Abstract SIDDHARTA-2 is a state-of-the-art experiment designed to perform measurements of kaonic atoms, which are exotic atoms composed of a negatively charged kaon orbiting nucleus. These atoms constitute an exceptional probe for investigating the strong interaction in the non-perturbative regime involving strangeness. …
