Kaonic Atom X-ray Spectra
- Stefan Meyer Institute of the Austrian Academy of Sciences, 1090 Vienna, Boltzmnanngasse 3 (Austria)
In kaonic atoms energy displacement and broadening of states result from the strong interaction. The most simple kaonic atoms like kaonic hydrogen and deuterium open the possibility to measure this strong interaction induced shift and width by x-ray spectroscopy. In the SIDDHARTA experiment al LNF (Frascati) the DA{phi}NE electron-positron collider delivers nearly mono-energetic negatively charged kaons from {phi} meson decay. This unique kaon source is used to form kaonic atoms. New high performance x-ray detectors (silicon drift detectors) arranged in an array allow x-ray spectroscopy with high energy resolution combined with timing capability. High precision x-ray measurements like SIDDHARTA at LNF will open the way to study the low energy regime of the strong force in the antikaon-nucleon interaction. The experiment and its current status is presented in this talk.
