2550 interactions of 12 C in emulsion at 4.5 A GeV / c have been used to study the properties of projectile fragments. The multiplicity and projected angular distributions of projectile fragments in different target groups have been studied. The production cross section of the reaction in which projectile 12 C breaks up into two Z = 3 fragments is found to be 6.6 × 10 −3 of the total inelastic cross section. The projected angular distributions of fragments exhibit features of limiting fragmentation. Statistically significant azimuthal correlations among fragments in the azimuthal plane indicates that the fragmenting nucleus gets a transverse momentum during the collision.

A nuclear photographic emulsion method was used to study the charge-state, ionization, and angular characteristics of secondaries produced in inelastic interactions of 56 Fe nuclei at 1.8 GeV/nucleon with H, CNO, and AgBr nuclei. The data obtained are compared with the results of calculations made in terms of the Dubna version of the cascade evaporation model (DCM). The DCM has been shown to satisfactorily describe most of the interaction characteristics for two nuclei in the studied reactions. At the same time, quantitative differences are observed in some cases.

Fragmentation Cross-sections of $^{32}$S at 0.7-{GeV}/nucleon, 1.2-{GeV}/nucleon and 200-{GeV}/nucleon

We used CR39 plastic nuclear track detectors (C12H18O7) in combination with automatic track measurement techniques to determine total charge changing and partial cross sections for the production of fragments of chargeZ F =6 toZ F =15 in collisions of32S beam nuclei at energies of 0.7, 1.2 and 200 GeV/nucleon in targets H, C, CR39, CH2, Al, Cu, Ag and Pb. By application of factorization rules measured partial cross sections are separated into pure nuclear and electromagnetic components. Total and partial cross sections for electromagnetic dissociation are compared with theoretical models. The energy dependence of pure nuclear cross sections is investigated.
