Hello,
For two spin 1/2 identical particles, the triplet state is:
|UP,UP>
1/√2 (|UP,DOWN> + |DOWN,UP>)
|DOWN,DOWN>
Q1: in the up,up or down,down, are the two electrons considered to have the same spin quantum number?
Q2: If so, then only the middle one (see above) is where they have different spin quantum numbers, right?
Q3: In the Singlet state, they have different spin quantum numbers, right?
