Electromagnetic dissociation cross sections for one, two, and three nucleon removal were measured for an {ital E}{sub lab}/{ital A}=14.6 GeV {sup 28}Si beam impinging on {sup 27}Al, {sup 120}Sn, and {sup 208}Pb targets. The measured cross sections exhibit an approximate {ital Z}{sub {ital T}}{sup 2} dependence and are well reproduced by calculations convoluting the virtual photon spectrum with the experimental {sigma}({gamma},{ital N}) photonuclear cross sections. Comparison with other experimental results and energy dependence of the cross sections are discussed.
