Fermions Bosons electron photon proton helium nuclei neutrons hydrogen atoms The symmetriza?on postulate works for composite systems as well of different types of fermions (bosons). Consider H2: Wavefunc?on for electrons must be an?symmetric under exchange, AND also the wavefunc?on for the two protons. This gives us a first stepping stone into understanding the quantum states of molecules. Pauli exclusion principle •  Pauli in trying to explain periodic...
