The measurements, which rely on the $\\pi^+\\pi^-$ decay channel, are presented in three regions of rapidity covering the range $|y|<0.8$. For each rapidity interval, cross sections are shown for different nuclear-breakup classes defined according to the presence of neutrons measured in the zero-degree calorimeters. The results are compared with predictions based on different models of nuclear shadowing. Finally, the observation of a coherently produced resonance-like structure with a mass around 1.7 GeV/$c^2$ and a width of about 140 MeV/$c^2$ is reported and compared with similar observations from other experiments.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.95218.v1/t1","@type":"Dataset","description":"Differential cross section as a function of rapidity for coherent RHO0 photoproduction in ultra-peripheral Pb-Pb collisions at ALICE.","name":"Table 1"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1782227?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/95218"}],"inLanguage":"en","name":"Coherent photoproduction of $\\rho^{0}$ vector mesons in ultra-peripheral Pb-Pb collisions at $\\sqrt{s_{\\rm NN}} = 5.02$ TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1782227?version=1","version":1}
