Kaonium

edit

The term "kaonium" is used for different exotic atoms and one has to be careful to distinguish them. In the sited paper from Krewald et al. the kaonium as a electromagnetically bound state of a positively charged kaon and a negatively charged antikaon (K+K-) is considered and the lifetime was calculated for this atom not for kaonic hydrogen (pK-) mentioned in this article.—Preceding unsigned comment added by 12.151.120.81 (talkcontribs) 15:31, 14 July 2006
