First measurement of kaonic helium-3 X-rays

The first observation of the kaonic (3)He [Formula: see text] transition was made, using slow [Formula: see text] mesons stopped in a gaseous (3)He target. The kaonic atom X-rays were detected with large-area silicon drift detectors using the timing information of the [Formula: see text] pairs of ϕ-...

Descripción
Sumario:The first observation of the kaonic (3)He [Formula: see text] transition was made, using slow [Formula: see text] mesons stopped in a gaseous (3)He target. The kaonic atom X-rays were detected with large-area silicon drift detectors using the timing information of the [Formula: see text] pairs of ϕ-meson decays produced by the DAΦNE [Formula: see text] collider. The strong interaction shift of the kaonic (3)He 2p state was determined to be [Formula: see text].
