WebSep 25, 2024 · 7.6: Spherical Harmonics. The simultaneous eigenstates, Yl, m(θ, ϕ), of L2 and Lz are known as the spherical harmonics . Let us investigate their functional form. We know that L + Yl, l(θ, ϕ) = 0, because there is no state for which m has a larger value than + l. http://theory.caltech.edu/~preskill/ph229/notes/chap4.pdf
