Measurements of the strong-interaction widths of the kaonic (3)He and (4)He 2p levels
{{output}}
The kaonic (3)He and (4)He X-rays emitted in the [Formula: see text] transitions were measured in the SIDDHARTA experiment. The widths of the kaonic (3)He and (4)He 2p states were determined to be [Formula: see text], and [Formula: see text], respectively. Bot... ...
