abstract
The X-ray transition yields of kaonic atoms produced in Kapton polyimide (C22H10N2O5) were measured for the first time in the SIDDHARTA experiment. X-ray yields of the kaonic atoms with low atomic numbers (Z = 6, 7, and 8) and transitions with high principal quantum numbers (n = 5-8) were determined. The relative yield ratios of the successive transitions and those of carbon-to-nitrogen (C:N) and carbon-to-oxygen (C:O) were also determined. These X-ray yields provide important information for understanding the capture ratios and cascade mechanisms of kaonic atoms produced in a compound material, such as Kapton.

Kaonic Copper and Fluorine Absolute Yields Measurement with a CZT-based Detection System at DA$\Phi$NE
Absolute X-ray yields measured for kaonic copper and fluorine transitions using CZT detectors at DAΦNE, with observed suppression of the 4→3 yield in fluorine yielding a lower limit on strong-interaction width.
