Two Identical Particles w/ Spin State s

[degerativpart]

what would the system of two identical paritcles with a spin, let's say s? I figure its different for symmetrical and anti-symmetrical spin states but how do you deal with the defined spin state s.

 

[Meir Achuz]

It depends on the spin of the particles. 1/2 + 1/2 = 1 is symmetric,
but 1+1=1 is antisymmetric.

How is 1 + 1 = 1?
The definition of an antisymmetric spin means that they are in different energy states.
S+1/S -- isn't this the ratio of symmetric to antisymm spins? How would you even begin to prove this?

 

[malawi_glenn]

It depends on the hamiltonian which energy the different spin states posess!

1+1 = 1, if one does vector sum.
