Hello. I found this forum when i was looking for some help with the following problem:(adsbygoogle = window.adsbygoogle || []).push({});

---------------------------------------------------------------

There are 3 neutrons (s=1/2). The hamiltonian of the system is:

H = S^2 - Sz^2 - (3/2)hbar^2

I need to found the possible states and energies.

----------------------------------------------------------------

The functions must be antisymetrical, right? But there is no spatial dependence in H.

So, the spin functions must be antisymetrical?

In that case, I don't know how do spin functions look like.

(S=S1+S2+S3 and Sz=Sz1+... are the operators of the total spin).

I'd be really greatfull if somebody help me with this.
