Writing sin^2 theta * Sin 2 phi in terms of spherical Harmonics

  • #1
I am trying to write the term "Sin^2 theta * Sin 2 phi" in terms of spherical Harmonics (they form a combination of Y(2,-2) and Y(2,2)) but the term I get contains the imaginary number 'i'. Am I doing something wrong.. In fact this term is a part of a Hamiltonian and when I get the eigenvalues I find that some are complex! What is happening?


Thanks

It is very hard to tell what you are doing wrong if you don't show explicit the work you have done and how you motivate the steps.
