We report the results on the electromagnetic dissociation of 14.5A GeV28Si and 200A GeV16O projectiles in nuclear emulsion. The overall charge changing production cross sections are determined experimentally and are found to agree reasonably well with those computed theoretically. The relative rate as a function of decay energy for various reaction channels are parameterized in terms of an exponential function. Majority of the events in the most prominent decay modes can be attributed to the excitation of giant dipole resonances. Multiplicity distributions of α particles emerged from nuclear as well as electromagnetic interactions are also investigated.

Electromagnetic dissociation.

The cross section is calculated from the relation sigma=f/ro*lambda, were ro=7.898*10**22 atoms per cm**3 and f is a weight factor which is unity for nuclear interactions produced by all the emulsion targets, for AG f=0.62.
