[en] The anomalous dimensions of the composite scaling operators for the nonlinear σ-model of symmetry G(m₁+m₂)/G(m₁) . G(m₂) calculated in the previous paper are expressed in terms of the group characters of the Young tableaux which classify these operators. As an application the exponents for the averaged moments of the wave functions and the crossover exponents for the Anderson localization are determined. Comparison with numerical calculations shows that the four-loop order contribution to the exponent of the participation ratio yields an overestimate, but of the expected sign. (orig.)
