WebJul 8, 2024 · For two fermions there are four spin states: αα, ββ, αβ, βα The first two are symmetric, the last two are not symmetric or antisymmetric when electrons are exchanged so linear combination has to be made. spin paired total spin=0, antisymmetric χ − := 1 2 [ α ( 1) β ( 2) − α ( 2) β ( 1)] and three triplet states with total spin=1, symmetric WebThe first excited state is one in which one of the electrons has n=1 (lowest single particle level) and one of the electrons has n=2 (first excited single particle level). In this case, either spin is okay for either electron. So there are four states: (n=1,up; n=2,up), (n=1,up; n=2, down), (n=1,down; n=2, up), (n=1,down; n=2,down).
