title: Theoretical contributions to coherent pion production in subthreshold and relativistic heavy-ion collisions.
abstract: The analytic results from a microscopic calculation for pion production in heavy-ion collisions at intermediate to relativistic energies both above and below pion threshold are presented and the most important terms that contribute to the pion spectrum are determined.  The energy dependence and the effects on the pion spectrum due to the various parameters in the theory are examined.  The model is applied to coherent pion-production in 16O + 12C collisions.
