Discussion Overview

The discussion revolves around the concept of a dineutron, a hypothetical particle consisting of two neutrons. Participants explore its existence, the implications of nuclear reactions involving dineutrons, and the relevance of the Pauli exclusion principle in this context.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant seeks clarification on the definition of a dineutron and its role in nuclear reactions, specifically asking for a reaction formula.
  • Another participant asserts that a dineutron does not exist and is not bound, suggesting that the information on Wikipedia may be misleading.
  • A third participant reiterates that a dineutron cannot exist in nature due to the Pauli exclusion principle, which they believe rules out the possibility of two identical particles being bound together.
  • A later reply challenges the assertion regarding the Pauli exclusion principle, arguing that while the dineutron is not bound, it does not mean that two identical particles cannot form a bound state under certain conditions.

Areas of Agreement / Disagreement

Participants express disagreement regarding the existence of the dineutron and the implications of the Pauli exclusion principle. Some assert that it cannot exist, while others suggest that it could potentially be bound under specific circumstances.

Contextual Notes

The discussion highlights the complexity of the dineutron's existence and the conditions under which identical particles may or may not be bound, indicating a need for careful consideration of definitions and principles in nuclear physics.

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

A dineutron is a hypothetical particle consisting of two neutrons that was suggested to have a transitory existence in nuclear reactions produced by helions that result in the formation of a proton and a nucleus having the same atomic number as the target nucleus but a mass number two units greater

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.
