Two-source emission of nuclear fragments in high energy collisions

The gamma -moments of the charge distributions of projectile fragments in s ulphur fragmentation at 200A GeV are obtained by using the Monte Carlo part ition method based on a two-source emission picture. Whence, the correlatio n between the gamma -moments can be obtained. The distributions of the gamm a -moments are investigated. We have also calculated the correlations betwe en the conditional moments (S-moments and gamma -moments) and the multiplic ity, the conditional moments and the bound system charge, the heaviest frag ment charge and the multiplicity, the heaviest fragment charge and the boun d system charge, as well as the distributions of the multiplicity and bound system charge. All of the calculated results are in agreement with the exp erimental data of nuclear diffractive excitation and electromagnetic dissoc iation of sulphur nuclei in nuclear emulsion at 200A GeV.
