Nucleon hard-core repulsion refers to the strong, short-range force that acts between nucleons (protons and neutrons) when they are extremely close together, preventing them from occupying the same space. This repulsive interaction is crucial in determining the overall size and stability of atomic nuclei, as it balances the attractive nuclear force that holds nucleons together at slightly larger distances. Understanding this repulsion helps explain why nuclei have specific sizes and how their mass is affected by the arrangement of nucleons within them.
congrats on reading the definition of nucleon hard-core repulsion. now let's actually learn it.
