2012, Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy PhysicsCitation Excerpt :The X-ray events were selected using this timing information, to obtain a good signal-to-background ratio in the energy spectra of kaonic atom X-rays without reducing their statistics [7,10]. Combined with the results of the shift values determined in [7], the correlations of the shift and width values of the kaonic 3He and 4He 2p states are plotted in Fig. 5, together with the average value reported in [1,2], where the error bars were calculated by adding the statistical and systematic errors quadratically. Clearly, the new results gave significantly smaller values both for the shift and width.
