We report on the first measurement of Mutual Coulomb Dissociation in heavy ion collisions. We employ forward calorimeters to measure neutron multiplicity at beam rapidity in peripheral collisions. The cross-section for simultaneous electromagnetic breakup of Au nuclei at √(s_NN)=130 GeV is σ_MCD=3.67± 0.25 barns in good agreement with calculations.
