The discussion focuses on the normalization of combined spins from three spin-1 particles. The user is trying to achieve a spin state |32> using specific combinations of states and is questioning whether to use Clebsch-Gordan coefficients for normalization. They clarify that their initial approach was flawed due to misrepresentation of spins and mention that guidance from their professor simplified the problem. The user acknowledges the complexity of combining three spins with total magnetic quantum number M_S=2 and whether |32> is the only possible state. Overall, the conversation highlights the challenges of spin combination and normalization in quantum mechanics.

Homework Statement
Find the normalized spin states for three identical non-interacting bosons where two have m_s = 1, and one has m_s = 0
Relevant Equations
None
I am having trouble with the normalization part.
To get a spin ##|32>## state I could have the following possibilities
##C_1|111110> + C_2|111011> + C_3|101111>##

This should be equivalent to
##C_1|11>|21> + C_2|11>|21> + C_3|10>|22>##
That is a spin 1 particle and a spin 2 particle that need to be combined.
So, to get the normalization coefficients would I just look these up in the Clepsch Gordon Table and that's all?

I would be careful here. If you add three spins ##S=1## with ##M_S=2##, is ##| 32\rangle## the only possibility?
 
Thanks, I see what the problem is, also I was using bad representation of the spins, this is from chapter 7 problem 7 in Sakurai 2nd ed. and the way my professor told me to do the problem made it a lot easier.
 
I want to find the solution to the integral ##\theta = \int_0^{\theta}\frac{du}{\sqrt{(c-u^2 +2u^3)}}## I can see that ##\frac{d^2u}{d\theta^2} = A +Bu+Cu^2## is a Weierstrass elliptic function, which can be generated from ##\Large(\normalsize\frac{du}{d\theta}\Large)\normalsize^2 = c-u^2 +2u^3## (A = 0, B=-1, C=3) So does this make my integral an elliptic integral? I haven't been able to find a table of integrals anywhere which contains an integral of this form so I'm a bit stuck. TerryW
