Total Angular Momentum of Many Particles

  1. Jun 26, 2008 #1
    Hi,

    How does one find the s=0 state for the addition of the spin of 4 (for example) electrons?

    More generally, how does one obtain the total spin of 4 electrons?

    I understand that for 2 electrons one can read the s=1 and s=0 states from a table of Clebsch-Gordan coefficients.

    To add 4 angular momenta, you can use something called Wigner 9j symbols. (Clebsch-Gordon coefficients are related to what are called 3j symbols; adding 3 angular momenta takes 6j symbols.)
