Abstract
Tomographic probability distributions (tomograms) for spin states of two particles with spin j 1 and j 2 are explicitly calculated. For a system of two spins, the relation of the state tomogram with total spin j and the spin projection m to tomograms of spin states with spin j 1 and j 2 and spin projections m 1 and m 2 is found. The tomographic probability distribution of the state of two particles with total spin j is calculated using the Clebsch-Gordan coefficients. The tomographic entropy of the state with total spin j is expressed in terms of 3j-symbols and matrix elements of irreducible representation of the SU(2) group.
