【 摘 要 】

The analysis of 2-dimentional Dalitz' diagram, measured in14C(π-, pd)X reaction, allowed to distinguish the pion absorption by p intranuclear cluster and to obtain an indication on the existence of3p +11Li configuration in14C nucleus. Highly excited states of12,13Be isotopes were found with the energy of Ex≈ 30 MeV for the first time. It was shown that these states decay as follows12Be∗→p +11Li and13Be∗→d +11Li.
