Coherent effects are considered in the model of bremsstrahlung of scalar pions in high-energy nucleus-nucleus collisions. As a result of the quantum mechanical Monte Carlo calculation it is shown that this mechanism yields pions in central collisions at large rapidities with a strong coherence. The coherent enhancement of the cross section has a threshold character of a function of the number of interacting nucleon pairs. The coherence narrows regions of pion transverse momenta towards zero and longitudinal momenta around some characteristic value. The pion pseudorapidities are moved to large values of about one-half of a unit. {copyright} {ital 1996 The American Physical Society.}
