In this report we give the results of the search for Cerenkov-like radiation features in pion production in nucleus-nucleus collisions at the Dubna energies. The spike-center distributions are obtained to exhibit the structure expected from coherent gluon-jet emission dynamics. The energy distribution within spikes is found to have a significant peak over the exponentially decreasing inclusive spectrum. The value of the peak energy and its width are in a good agreement with those expected for pions produced model.
