Soft photon registration at Nuclotron

First results of a soft photonyield in nucleus-nuclear interactions at 3.5 GeV per nucleon are presented. These photons have been registered at Nuclotron(LHEP, JINR) by an electromagnetic calorimeterbuilt in the SVD Collaboration. The obtained spectra confirm the excess yield in the energy region less than 50 MeV in comparison with theoretical predictions and agree with previous experiments at high-energy interactions.
