Discussion Overview
The discussion centers on the neutron capture cross section of tritium (3H) and the existence of the hypothetical nucleus 4H (quadrium). Participants explore the implications of these assertions regarding neutron interactions and the stability of 4H.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
Main Points Raised
- One participant asserts that the neutron capture cross section of tritium is zero for all neutron energies, suggesting that this implies the non-existence of 4H.
- Another participant references Wikipedia, claiming that 4H exists as a very short-lived nucleus and can be produced via the reaction 3H+n, although they note that deuterium is a more practical option for experiments.
- A different participant expresses uncertainty about the implications of 4H's decay process, which involves ejecting a neutron almost immediately, and questions its relevance in behavioral models.
- Another participant discusses the similarity of (n,total) and (n,elastic) cross-sections for tritium, concluding that the absorption cross-section is negligible, reinforcing the idea that 4H effectively does not exist.
Areas of Agreement / Disagreement
Participants express differing views on the existence of 4H, with some asserting it does not exist in a useful sense while others suggest it can be produced, indicating a lack of consensus on this topic.
Contextual Notes
Participants reference various sources, including the NNDC and Wikipedia, but there are unresolved questions regarding the definitions and implications of neutron capture and the stability of 4H.
