Fundamental interactions two admit the given model only:
- Electromagnetic.
- Gravitational.
So-called "weak interaction" and "strong interaction" are secondary:
- It is possible to term as "weak interaction" an orbital motion of
and their subsequent
-decay.
- It is possible to term as "strong interaction" a
donor-acceptor
interaction of orbital
plus a simultaneous spin-spin interaction of the central particles.
For example, nucleons in a atomic nucleus or pions in a proton.
