## Homework Statement

What s the inner product [tex]<2011|0011>[/tex]

## Homework Equations

[tex]C_{m_1m_2}=<l_1l_2m_1m_2|lml_1l_2>[/tex]

## The Attempt at a Solution

I'm not sure how to exactly solve this question. The first thing that came to my mind was the Clebsch-Gordan equation, since that's what it looks like, but then I saw that it doesnt really make any sense because of this:

[tex]|lml_1l_2>=|0011>[/tex]

[tex]|l_1l_2m_1m_2>=|2011>[/tex]

I'm guessing the inner product is zero, but i'm not sure how to show this.

maybe because since m=0, m_1=1 and m_2=1 wouldnt make sense? not too sure, any help would be appreciated.

thanks,
