SUMMARY
The discussion centers on calculating the nuclear repulsive force between protons and neutrons at short distances, specifically at 0.5 femtometers (fm). It is established that there is no simple formula for this calculation. Two primary methods are highlighted: the traditional approach using nuclear potentials derived from nucleon-nucleon scattering and the modern method based on chiral symmetry, which utilizes Quantum Chromodynamics (QCD) and hadrons. Reference materials include Wikipedia and specific arXiv papers for further reading.
