| Popis: | The formation of the excited states $^{12}$C(0$^+_2$) and $^{12}$C(3$^-$) is investigated in the dissociation of $^{12}$C $\to$ 3$\alpha$ and $^{16}$O $\to$ 4$\alpha$ 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 $^{12}$C(0$^+_2$) and $^{12}$C(3$^-$) to the dissociation $^{12}$C $\to$ 3$\alpha$ is 11 and 19%, and in $^{16}$O $\to$ 4$\alpha$ it is - 20 and 30%, correspondingly. Comment: The article to be published in Physics of atomic Nuclei as proceedings of The 7th International Conference on Particle Physics and Astrophysics (ICPPA-2024) (https://indico.particle.mephi.ru/event/436/contributions/4186/) |
