Title: GR9677.033
Post by: conantee on December 07, 2010, 12:06:20 AM
33. A diatomic molecule is initially in the state \Psi(\Theta, \Phi) = (5Y_1^1+3Y_5^1+2Y_5^{-1})/(38)^\frac{1}{2}, where Y_l^m is a spherical harmonic. If measurements are made of the total angular momentum quantum number l and of the azimuthal angular momentum quantum number m, what is the probability of obtaining the result l = 5?
(A) 36/144
(B) 9/38
(C) 13/38
(D) 5/(38)^\frac{1}{2}
(E) 34/38
