The formation of the excited states 12C(0+2) and 12C(3-) is investigated in the dissociation of 12C → 3α and 16O → 4α at the energy of 3.65 GeV per nucleon in the nuclear emulsion. The identification becomes possible by 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 12C(0+2) and 12C(3-) to the dissociation 12C → 3α is 11 and 19%, and in 16O → 4α it is - 20 and 30%, correspondingly.
