Preliminary results of the study of ultraperipheral (gamma gamma and \gpom) interactions are presented. The analysis was performed with the data recorded by the ATLAS experiment during the LHC Pb-Pb run in 2011. The data, taken at the beam energy of 2.76 TeV per nucleon, correspond to an integrat luminosity of 152 micro b-1. Muon pairs, produced in pure electromagnetic two-photon interactions and in reactions of J/psi photoproduction, were analysed. A preliminary cross section for the AA to AA plus mu mu reactio has been determined from these studies.
