Abstract

First results of the study of a soft photon yield in nucleus-nucleus collisions at 3.5 GeV per nucleon at Nuclotron (LHEP, JINR) are presented. These photons are registered by an BGO electromagnetic calorimeter built by the SVD-2 Collaboration. The obtained spectra confirm the excessive yield in the energy region less than 50 MeV in comparison with theoretical estimations and agree with previous experiments at high-energy interactions.
