Electromagnetic dissociation ofS32at ultrarelativistic energy in nuclear emulsion

Electromagnetic dissociation of 200 GeV/nucleon ${}_{}{}^{32}{}_{}{}^{}\mathrm{S}$ projectiles has been investigated in nuclear emulsion. It constitutes about 15% of the total number of events observed. The production cross section for the electromagnetic process has been found to increase with the projectile charge when compared with that of the ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ beam at the same energy per nucleon.
