Abstract

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