The electromagnetic dissociation of /sup 59/Co and /sup 197/Au target nuclei by 1.26 GeV/nucleon /sup 139/La projectiles was inferred from measurement of cross sections for the one-neutron removal reaction. The corresponding electromagnetic dissociation cross sections are large, reaching 0.28 +- 0.04 and 1.97 +- 0.13 barns for the /sup 59/Co(/sup 139/La,X)/sup 58/CO and /sup 197/Au(/sup 139/La,X)/sup 196Au/ reactions, respectively. The experimental cross sections in excess of the estimated nuclear contributions are generally well described by use of the Weizsaecker-Williams method for calculating the electromagnetic dissociation contributions, but they appear to increase more slowly as the projectile charge is increased, consistent with a trend observed earlier for lower-Z projectiles.
