A detailed study of the electromagnetic dissociation of {sup 28}Si in extremely peripheral collisions at 14.6 GeV/nucleon was carried out with {sup 28}Si projectiles interacting on Pb, Sn, Cu and Al targets. The excitation energy is determined by measurements of the invariant mass of the excited system. We examine the decay channels 1p+{sup 27}Al, l+{sup 27}Si and 2p+{sup 26}Mg. The excitation energy distributions are well reproduced by combining the photon spectrum calculated using the Weizsaecker-Williams approximation with the experimental data on the photonuclear cross sections. No evidence for double photon excitation of {sup 28}Si is observed.
