THE INVESTIGATION OF FRAGMENTATION (Z=2) OF RELATIVISTIC NUCLEI 16�? AND 208Pb

Kotikov EA

The angular distributions of double charged fragments of a nucleus 16�? with the momentum 4.5А GeV c-1 and 208Pb with the momentum 160А GeV c-1 were studied during their interaction with photoemulsion nuclei. 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 double charged fragments of these nuclei are not described by this model.
