Flernukleonpotentialer

Flernukleonpotentialer is a theoretical class of interaction potentials used in speculative nuclear models to describe forces between constituents in extended-nucleon frameworks. The term appears primarily in fictional or exploratory discussions and is not part of mainstream nuclear physics. In these contexts, the potentials describe the potential energy as a function of separation and internal degrees of freedom, guiding the dynamics of the two-body system.

Typical structure decomposes into central, spin-dependent, and tensor components. The central part sets the overall attraction or repulsion and often features a short-range repulsion and a medium-range attraction. Spin-dependent terms couple to the spins of the interacting constituents, and tensor terms induce orientation-dependent forces that can mix partial waves.

Common modelling choices include Yukawa-type forms inspired by meson exchange, Gaussian expansions, and chiral-inspired kernels. Parameters are chosen to reproduce abstract targets such as synthetic phase shifts or bound-state energies within a toy model, rather than experimental data.

Applications are primarily pedagogical and in-silico: two-body scattering in toy theories, bound-state spectra, and qualitative studies of many-body systems under extended-nucleon hypotheses. As with any speculative framework, results depend strongly on model assumptions and lack direct experimental verification.
