Abstract :
We present in this paper the characteristics of the BaF 2 spectrometer, TAPS, which allow to detect rare electromagnetic events in a high hadronic background. The case of deep subthreshold pions produced in 36 Ar+ 197 Au collisions at 25A and 35A MeV, in which the pion signal is much weaker than the hadronic background and comparable to the cosmic ray background, is studied.
