G. coefficients. G. coefficient 17 vanishes unless m1 + m2 = m. G. coefficients and why are they so called? G. coefficient related to the Wigner 3j symbol? G. 2 Two particles are in the triplet state (S=1). Construct their coupled spin function in terms of the spin states of the individual particles. G. coefficients and find their values. 3 Write down the spin-orbit coupled wave function for a p-electron in an atom. G. coefficients. G. coefficients. 6 Starting from the spin-orbit coupled wave function of spin- particle and using the lowering operator repeatedly, determine the coupled wave functions, denotes the spherical harmonic and a the spin-up state.

Series). 5. G. series (Eq. G. coefficients. Multiplying both sides of Eq. 49) was obtained by applying the orthonormality condition (Eq. G. coefficients. G. series. There is an alternative way of obtaining this series. The alternative method is to start from the following coupling rule of two angular momenta. 51) 50 CHAPTER 5 Rotate the coordinate system through the Euler angles α,β, γ. 55) which is the same as Eq. 50). G. series can be used to if the rotation generate the elements of all the matrices Dj(ω), ( j (j > matrix is given.
