Ultra-peripheral Collisions with the ATLAS Detector
  The first ATLAS measurement of ultra-peripheral collisions is described. Dimuon pairs from photon--photon scattering have been measured with data of Pb+Pb collisions at $\sqrt{s_{\mathrm{NN}}} = 5.02$ TeV taken with the ATLAS detector at the LHC. The measured cross-section is presented as a function of dimuon invariant mass and rapidity and is well described by STARLIGHT 1.1 calculations. This measurement paves the way for new studies of photon-induced reactions at the LHC.
