I've just come across the spin states of a two electron system. There are 4 states possible and I am a little confused as to why the state below has values of s=1 m_s=0?
where α(i) and β(i) tell us if the particle has +ve or -ve z component of spin respectively.
I'm going through a derivation and it shows: (dirac notation)
V and A are operators that are hermition and commute with each other and ana and anb are the eigenvalues of the operator A. I imagine it is trivial and possibly doesn't even matter but why does...
