Neutronium

Neutronium is a hypothetical form of matter, which consists solely of neutrons and the density would be comparable to that of atomic nuclei.

The term was coined in 1926 by chemist Andreas von Antropoff, even before the discovery of the neutron, coined to designate a hypothetical chemical element with the atomic number 0, which he placed at the head of the Periodic Table. The term was subsequently used frequently in science fiction literature. After the discovery of the neutron star, which consist predominantly of degenerate neutrons and actually have the density of atomic nuclei, designated to their state of matter in science occasionally with neutronium.

Occasionally there were scientific reports that there were next to free neutrons also under approximately normal conditions at least as an intermediate stage of nuclear reactions short-lived bound neutrons:

• The composite of two neutron Dineutron
• , which consists of four neutrons Tetraneutron and
• More neutron cluster.

However, such experiments could never be confirmed, and calculations show that these neutrons cluster as well, which consists of five neutrons Pentaneutron - do not have a bound state and therefore do not exist.
