    "abstract": "We study the peripheral ion collisions at LHC energies in which a nucleus is\nexcited to the discrete state and then emits $\\gamma$-rays. Large nuclear\nLorenz factor allows to observe the high energy photons up to a few ten GeV and\nin the region of angles of a few hundred micro-radians around the beam\ndirection. These photons can be used for tagging the events with particle\nproduction in the central rapidity region in the ultra-peripheral collisions.\nFor that it is necessary to have an electromagnetic detector in front of the\nzero degree calorimeter in the LHC experiments.",
