Searching for rare cluster configurations of 14C nuclei in the pion absorption reaction

Analysis of the two-dimensional Dalitz plot measured in the reaction 14 C(π – , pd ) X allows us to follow the absorption of pions by cluster 3 p and identify signs of the configuration 3 p + 11 Li in the 14 C nucleus. The highly excited state of 12,13 Be beryllium isotopes with excitation energies...

Zusammenfassung:	Analysis of the two-dimensional Dalitz plot measured in the reaction 14 C(π – , pd ) X allows us to follow the absorption of pions by cluster 3 p and identify signs of the configuration 3 p + 11 Li in the 14 C nucleus. The highly excited state of 12,13 Be beryllium isotopes with excitation energies E * ≈ 30 MeV and which decay with the emission of hydrogen isotopes is observed for the first time: 12 Be* → p + 11 Li and 13 Be* → d + 11 Li.
