      abstract     = {This paper describes a measurement of light-by-light
                      scattering based on Pb+Pb collision data recorded by the
                      ATLAS experiment during Run 2 of the LHC. The study uses 2.2
                      nb$^{−1}$ of integrated luminosity collected in 2015 and
                      2018 at $ \sqrt{s_{\mathrm{NN}}} $ = 5.02 TeV.
                      Light-by-light scattering candidates are selected in events
                      with two photons produced exclusively, each with transverse
                      energy $ {E}_{\mathrm{T}}^{\gamma } $> 2.5 GeV,
                      pseudorapidity |η$_{γ}$| < 2.37, diphoton invariant mass
                      m$_{γγ}$> 5 GeV, and with small diphoton transverse
                      momentum and diphoton acoplanarity. The integrated and
                      differential fiducial cross sections are measured and
                      compared with theoretical predictions. The diphoton
                      invariant mass distribution is used to set limits on the
                      production of axion-like particles. This result provides the
                      most stringent limits to date on axion-like particle
                      production for masses in the range 6–100 GeV. Cross
                      sections above 2 to 70 nb are excluded at the 95\% CL in
                      that mass interval.[graphic not available: see fulltext]},
