We study mutual dissociation of heavy nuclei in peripheral collisions atultrarelativistic energies. Earlier this process was proposed for beamluminosity monitoring via simultaneous registration of forward and backwardneutrons in zero degree calorimeters at Relativistic Heavy Ion Collider.Electromagnetic dissociation of heavy ions is considered in the framework ofthe Weizsacker-Williams method and simulated by the RELDIS code. Photoneutroncross sections measured in different experiments and calculated by the GNASHcode are used as input for the calculations of dissociation cross sections. Thedifference in results obtained with different inputs provides a realisticestimation for the systematic uncertainty of the luminosity monitoring method.Contribution to simultaneous neutron emission due to grazing nuclearinteractions is calculated within the abrasion model. Good description of CERNSPS experimental data on Au and Pb dissociation gives confidence in predictivepower of the model for AuAu and PbPb collisions at RHIC and LHC.Comment: 46 pages with 7 tables and 13 figures, numerical integration accuracy  improved, next-to-leading-order corrections include
