Hypernucleus

A hypertext is a core nucleus, which still contains at least one hyperon and thus a strange quark except nucleons (protons and neutrons). This includes Hypernuclei to Strange Matter.

Hypernuclei, for example, generated by the exchange reaction

With a kaon called a pion.

To denote the Hypernuclei the symbol of the hyperon is given as an index. A 5ΛHe is for example a core consisting of five baryons - the two protons and neutrons, and a Λ particles.

Hypernuclei light elements that contain the lightest hyperon, the Lambda baryon, are relatively long-lived with lifetimes around 10-10 s, since the lambda can only decay via the weak interaction. Therefore, it is possible to investigate such Hypernuclei more accurate, to operate nuclear spectroscopy on them. In some sigma hypernuclei ( hypernuclei with Sigma baryons, the nächstschwereren hyperons ), this is also done. Hypernuclei are therefore suitable to study the behavior of individual particles within atomic nuclei. While there is indistinguishable in "normal" nuclei N neutrons and Z protons indistinguishable, one has in hypernuclei with the hyperon in the form of this " marked " particle in a sense a "probe" in the nucleus. This corresponds roughly to muonic atoms to which you want to obtain information about the atomic shell.
