  We study the transverse momentum spectra of fermions and bosons produced in
strong, time-dependent abelian field. The transverse size of the abelian field
is finite, similarly to color strings and ropes. Different time-dependent field
strengths are investigated in a kinetic model, and transverse momentum spectra
are calculated for fermions and bosons. These spectra display exponential or
polynomial behavior at high p_T, depending on the given time dependence. We
compare our spectra to lattice result for a classical gluon field and obtain
surprisingly good agreement in certain cases.
