Abstract

The nuclear emulsion method is applied to study binary dissociation leading to the formation of α-particles from 16O nuclei at 3.65 GeV per nucleon and 22Ne nuclei at 3.22 GeV per nucleon. The invariant mass distribution for the 16O→12C(0+1)+α channel indicates decays of the 16O(0+6) excitation, whose probability exceeds the estimate for the 12C(0+2)+α channel by a factor of 20. The invariant mass distribution for 22Ne→18O+α exhibits a peak corresponding to 22Ne excitations around 11.6 MeV.

AB  - The nuclear emulsion method is applied to study binary dissociation leading to the formation of α-particles from ^16O nuclei at 3.65 GeV per nucleon and ^22Ne nuclei at 3.22 GeV per nucleon. The invariant mass distribution for the ^16O→^12C(0^+_1)+α channel indicates decays of the ^16O(0^+_6) excitation, whose probability exceeds the estimate for the ^12C(0^+_2)+α channel by a factor of 20. The invariant mass distribution for ^22Ne→^18O+α exhibits a peak corresponding to ^22Ne excitations around 11.6 MeV.
