      abstract     = {Exclusive production of dielectron pairs,
                      $\gamma\gamma\rightarrow e^+e^-$, is studied using
                      $\mathcal{L}_\mathrm{int}=1.72\; \mathrm{nb^{-1}}$ of data
                      from ultraperipheral collisions of lead nuclei at
                      $\sqrt{s_{_{\text{NN}}}} = 5.02$ TeV recorded by the ATLAS
                      detector at the LHC. The process of interest proceeds via
                      photon-photon interaction in the strong electromagnetic
                      fields of relativistic lead nuclei. Dielectron production is
                      measured in the fiducial region defined by following
                      requirements: electron transverse momentum,
                      $p_{\textrm{T}}^{e} > 2.5$ GeV, absolute electron
                      pseudorapidity, $|\eta^{e}| < 2.5$, invariant mass of the
                      dielectron system, $m_{ee} > 5$ GeV, and transverse momentum
                      of the dielecton pair, $p_{\textrm{T}}^{ee} < 2$ GeV.
                      Differential cross-sections are measured as a function of
                      $m_{ee}$, average $p_{\textrm{T}}^{e}$, absolute rapidity of
                      the dielectron system, $|y_{ee}|$, and scattering angle in
                      the dielectron rest frame, $|\cos\theta^*|$ in the inclusive
                      sample, and also under the requirement of no activity in the
                      forward direction. The total integrated fiducial
                      cross-section is measured to be $215 \pm 1 \text{(stat.)}
                      ^{+23}_{-20} \text{(syst.)} \pm 4 \text{(lumi.)}\; \mu$b.
                      Within experimental uncertainties the measured integrated
                      cross-section is in good agreement with the QED predictions
                      from the Monte Carlo programs Starlight and SuperChic,
                      confirming the broad features of the initial photon fluxes.
                      The differential cross-sections show systematic differences
                      with these predictions which are more pronounced at high
                      $|y_{ee}|$ and $|\cos\theta^*|$ values.},
