  A complete expression for the p_T-distribution of the gluon production rate
in the homogeneous chromoelectric field has been obtained. Our result contains
a new additional term proportional to the singular function \delta(p_T^2). We
demonstrate that the presence of this term is consistent with the dual symmetry
of QCD effective action and allows to reproduce the known result for the total
imaginary part of the effective action after integration over transverse
momentum.
