  We calculate the mixed tensor susceptibility of QCD vacuum in the framework
of the global color symmetry model. In our calculation, the functional
integration over gluon fields can be performed and the gluonic vacuum
observable can be expressed in terms of the quark operators and the gluon
propagator. The mixed tensor susceptibility was obtained with the subtraction
of the perturbative contribution which is evaluated by the Wigner solution of
the quark gap equation. Using several different effective quark-quark
interaction models, we find the values of the mixed tensor susceptibility are
very small.
