    I am reading wikipedia term"dineutron" but i can not understand this sentence in red.

    http://en.wikipedia.org/wiki/Dineutron
    helion=He-3

    what is the reaction formula ? Thank you!

    I'm not sure what this means, and since anyone can edit Wikipedia, all sorts of nonsense can be found there.

    That said, it's known that there is no dineutron. It's not bound.

    Dineutron is nucleus which consist of two neutrons. Something like that don't exist in nature because Pauli exclusive principe rules!

    Not true. Oddly, you're the second person who has argued that the PEP precludes binding of two identical particles; I wonder if some textbook has it wrong or presents it in a confusing way. One can have a bound state of identical particles so long as no two particles are in the same state (strictly speaking, the entire wavefunction needs to be antisymmetric). The dineutron isn't bound, but that's not the same as saying it can't be bound.
