Description
An energy shift of the 2p level of kaonic 3He and 4He atoms is recently
studied in theory and experiment. A theory predicting deeply bound
kaonic nuclear states estimates a significant energy shift in kaonic
3He or 4He. The SIDDHARTA experiment measured the kaonic 3He and 4He
3d-2p X-ray transitions at the DAFNE e+e- collider. The strong interaction
shifts of the kaonic 3He and 4He 2p state were determined precisely.
The world's first observation of kaonic 3He was performed. In addition,
a possible isotope effect between 3He and 4He was obtained. In this talk,
the results of kaonic 3He and 4He X-ray measurements in the SIDDHARTA experiment will be presented, as well as future plans.
