The intense photon fluxes of relativistic nuclei provide a possibility tostudy photonuclear and two-photon interactions in ultra-peripheral collisions(UPC) where the nuclei do not overlap and no strong nuclear interactions occur.The study of such collisions provides information about the initial state ofnuclei. First ALICE results from the LHC Run 2 are presented for forwardexclusive \jpsi production in UPC, which is sensitive to the gluon distributionin nuclei. The increased statistics and the higher collision energy allows fora more detailed study at lower values of Bjorken-$x$. The analysis of the$\gamma+A \rightarrow \rho^0+A$ process in UPC is a tool to test the so-calledblack disk regime, where the target nucleus appears like a black disk and thetotal $\rho^0+A$ cross section reaches its limit. ALICE reports newmeasurements of \rrho photoproduction cross sections in Pb-Pb UPC at$\sqrt{s_{\rm NN}}=5.02$ TeV at mid-rapidity, which are compared topredictions.
