      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
                      $|\eta_{\gamma}| < 2.37$, diphoton invariant mass
                      $m_{\gamma\gamma} > 5$ 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.},
