Exchange symmetry of two identical spin-one-half fermions
ID: exchange-symmetry-of-two-identical-spin-one-half-fermions
For two identical spin-one-half fermions with no additional antisymmetric internal factor, the antisymmetric spin-one-half singlet state combines with an even- symmetric orbital state, while the symmetric spin-one-half triplet state combines with an odd- antisymmetric orbital state.
