The SIDDHARTA (SIlicon Drift Detector for Hadronic Atom Research with Timing Application) collaboration performed X-ray spectroscopy measurement of kaonic atoms at the DAΦNE e+ e− collider. Low energy negative kaons from DAΦNE ϕ-factory were stopped in gaseous targets to produce kaonic atoms. We employed specially designed Silicon Drift Detectors (SDDs) to detect the kaonic X-rays. Based on the energy of kaonic-4 He 3d→ 2p transition, we determined a new value of the 2p level strong-interaction shift of kaonic-4 He: 0±6 (stat.)±2 (syst.) eV [1]. Together with the result of recent E570 experiment [2] at the KEK-PS, a small shift (if any) of kaonic-4 He 2p level has become well established.
