Abstract
First results of study of a soft photon yield at Nuclotron (LHEP, JINR) in nucleus-nucleus collisions at 3.5 GeV per nucleon are presented. These photons are registered by an BGO electromagnetic calorimeter built by 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.
Highlights
Physicists consider that at interactions of nuclei with proton and deuteron beams are formed cold nuclear matter [1]

Summary
Physicists consider that at interactions of nuclei with proton and deuteron beams are formed cold nuclear matter [1]. To understand nature of the SP formation comprehensively and, in particular, to test relation between the SP excess yield and the BEC formation, the SP electromagnetic calorimeter (SPEC) has been manufactured and tested by the SVD Collaboration at U-70 accelerator [13]. This calorimeter is a stand-alone device and it differs from many similar ones by its extremely low energy threshold of gamma-quantum registration – of order of 2 MeV. The first preliminary spectra of SP obtained with the deuterium and lithium beams on a carbon target at Nuclotron are presented
