1. The problem statement, all variables and given/known data I need to know what the eigen value of Lx would be if, Lx|n,l,m>. 2. Relevant equations L+-=Lx+-iLy L2=Lx2+Ly2+Lz2 Lz|n,l,m>=mhbar|n,l,m> L|n,l,m>=l(l+1)hbar2|n,l,m> 3. The attempt at a solution I have a mixed state I need to apply Lx tp, but I'm not sure how! If anyone known how to put this in terms of L, Lz, or L+-, I would really appreciate the help!
