摘要：

formation of the unbound heavy helium isotopes He-7,He-9 was studied in the reactions of stopped pion absorption by light nuclei. Measurements were carried out using two-arm multilayer semiconductor spectrometer. The data on the level structures obtained in different reaction channels are consistent with each other. Our results on the energies and widths of the low-lying states of the He-7,He-9 are consistent with the world data. Record values of resonance energies were obtained for highly excited states of He-7 (24.5 MeV) and He-9 (10.5 MeV).
