SUMMARY

The discussion focuses on utilizing Clebsch-Gordan coefficients to determine the coefficients for a three-particle system, specifically three spin-1/2 particles. Participants seek methods to extract these coefficients from existing tables, particularly for the combined state |s12=0, S=1/2, ms=1/2>. The Wigner 3-j symbols are referenced as a critical resource for this calculation. The consensus is that while tables provide a foundation, additional computational methods may be necessary for complex combinations.

Is there a way to use the Clebsch Gordon coefficients tables to find the coefficients of a three particle system? For example if there is a system of three spin 1/2 particles, how to find the Clebsch Coefficients for different spin states using tables?(say for the state, |s12=0, S=1/2 ms=1/2>)
