Kaonium
Kaonium est atomus exoticus, qui in statu ligato kaonis onus positivum et kaonis onus negativum ferentis consistit. Kaonium in experimentis non observatum est, et theoria canonica physicae nuclearis kaonia vitam brevem, circa 10−18 secunda, habere existimat.<ref>Deloff 2003: sectio 10.3.</re>Krewald, Lemmer, et Sassen 2004: 016003.</ref>
