Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent handle nuclear reactions by type, reactants, energy and safety, and mark fringe claims such as cold fusion as unconfirmed.

A process in which one or more atomic nuclei change composition or energy through collision with another particle or nucleus, producing different nuclides; includes fusion, fission, transmutation and nucleosynthesis.

What it is for: Energy production, element creation in stars, isotope production and research.

It can be write and balance reaction equations; compute Q-values; study in accelerators and reactors; produce medical isotopes.

Distinguishing features

Changes atomic nuclei

Energy from mass difference

Governed by conservation laws

Some claimed reactions lack confirmation

What it looks like

Not visible; detected through particles and radiation.

How it is recognised

Reaction notation such as A(a,b)B

Types such as fusion or fission

Alchemy terms are historical, not physics

What the second pass must settle

  • Should reaction types be separate entries?
  • How should reaction data be linked?
  • How should fringe claims be marked?
