Abstract: (Elsevier)
The strong interaction widths, shifts and relative intensities have been measured for the last observed X-ray transitions in kaonic and pionic helium. The effect of the strong interaction on the 2p level in kaonic helium was much larger than anticipated from optical-model calculations. The energy shift of the 2p level was determined to be −35±12eV and the natural line width 30±30eV, whereas optical-model calculations predicted a shift and width of approximately 0.1 eV and 2.0 eV, respectively.
