The electromagnetic dissociation of /sup 59/Co, /sup 89/Y, and /sup 197/Au target nuclei was inferred from measurements of cross sections for the one-neutron removal reaction. Beams of 2.1 GeV/nucleon /sup 1/H, /sup 12/C, and /sup 20/Ne, 1.8 GeV/nucleon /sup 40/Ar, and 1.7 GeV/nucleon /sup 56/Fe projectiles were used. Beam intensities were monitored using the /sup 12/C(RHI,X)/sup 11/C reaction, where RHI represents relativistic heavy ion beams. The experimental cross sections in excess of the estimated nuclear contributions are generally well described by use of the Weizsaaumlcker-Williams method for calculating the electromagnetic dissociation contributions but increase more slowly as the projectile charge is increased. Cross sections for one-neutron removal reactions are large for the heavier projectiles, ranging up to 707 mb. For these cases a high percentage is from the electromagnetic dissociation process.
