Abstract : The ALICE Collaboration at the LHC has measured the j/psi and psi' photoproduction at mid-rapidity in ultra-peripheral Pb-Pb collisions at sqrt(sNN) = 2.76 TeV. The charmonium is identified via its leptonic decay for events where the hadronic activity is required to be minimal. The analysis is based on an event sample corresponding to an integrated luminosity of about 23 {\mu}b^{-1}. The cross section for coherent and incoherent j/psi production in the rapidity interval -0.9 < y < 0.9, are d{\sigma}_{J/{\psi}}^{coh}/dy = 2.38^{+0.34}_{-0.24}(sta+sys) mb and d{\sigma}_{J/{\psi}}^{inc}/dy = 0.98^{+0.19}_{-0.17}(sta+sys) mb, respectively. The results are compared to theoretical models for j/{\psi} production and the coherent cross section is found to be in good agreement with those models which include nuclear gluon shadowing consistent with EPS09 parametrization. In addition the cross section for the process {\gamma}{\gamma} -> e+e- has been measured and found to be in agreement with the STARLIGHT Monte Carlo predictions.
