Abstract: | The angular distributions of doubly charged fragments of 16O nuclei having a momentum of 4.5 GeV/c per nucleon and interacting with track-emulsion nuclei were studied. The experimental angular distributions of doubly charged fragments of a 16O nucleus are not described by the statistical model of the fragmentation of nuclei. The possible channels of fragmentation of 16O nuclei may include 16O → 28Be → 4α, 16O → 8Be +8 Be* → 4α, 16O → 28Be* → 4α, 16O → α+12C, 16O → α +12C* → α + 3α, 16O → α +12C* → α + pα 7Li, 16O → α +12C* → α + 26Li, 16O → α +12C* → α + pt2α, 16O → Li + B, and 16O → Li* + B*. |
