Abstract
We calculate the cross section for the production of a given number of neutrons in UPC of 208 Pb + 208 Pb. A simple model which takes into account the fact that only a part of the energy is available in the thermalized phase, proposed recently, is discussed. The results of the model calculation are compared with recent neutron ZDC ALICE measurements. The role of multiple photon exchanges is discussed.
