Editing Tetraneutron (section)

== Consequences of hypothetical bound tetraneutrons==
If, however, the existence of bound tetraneutrons were ever independently confirmed, considerable adjustments would have to be made to current nuclear models.  Bertulani and Zelevinsky proposed that, if it existed, the tetraneutron could be formed by a bound state of two [[dineutron]] systems.<ref name="bz03">
