Type: article
Abstract: The formation of the excited states $${}^{12}$$ C(0 $${}^{+}_{2}$$ ) and $${}^{12}$$ C(3 $${}^{-}$$ ) is investigated in the dissociation of $${}^{12}\textrm{C}\to 3\alpha$$ and $${}^{16}\textrm{O}\to 4\alpha$$ at the energy of 3.65 GeV per nucleon in the nuclear emulsion. The identification becomes possible through reconstructing the invariant mass from measurements of emission angles in the approximation of conservation of momentum per nucleon of the parent nucleus. The contribution of the decays $${}^{12}$$ C(0 $${}^{+}_{2}$$ ) and $${}^{12}$$ C(3 $${}^{-}$$ ) to the dissociation $${}^{12}\textrm{C}\to 3\alpha$$ is 11 and 19 $$\%$$ , and in $${}^{16}\textrm{O}\to 4\alpha$$ it is 20 and 30 $$\%$$ , correspondingly.
