Abstract :

The angular distributions of doubly charged fragments of a nucleus 16�? with the momentum 4.5А GeV c-1 and 208Pb with the momentum 160А GeV c-1 during their interaction with photoemulsion nuclei were studied. Contrary to common belief that fragmentation of relativistic nuclei in a wide range of masses and energy conforms to the statistical model, the experimental angular distributions of doubly charged fragments of these nuclei are not described by this model. The mechanisms of fragmentation of the oxygen nuclei can at least be assumed based on angle measurements and visual observation of all events of their inelastic interactions with emulsion nuclei. The lead nuclei fragmentation is associated with much more numerous processes. But it is not possible to identify them using the angular measurements only.
