摘要：

An estimate is made of the Landau-Pomeranchuk effect on the production of dileptons in a hadronic gas. For low-mass dilepton pairs this effect reduces the production rate for bremsstrahlung in a dense pion gas by an order of magnitude. For high invariant masses its influence is negligible. This behavior is of importance for the theoretical analysis of low-mass dilepton pairs produced in relativistic heavy ion collisions.
