© 2020 Published under licence by IOP Publishing Ltd.Formation of the 7He heavy isotope was studied in the reactions of stopped pion absorption by light nuclei 9Be, 10,11B and 12,14C. Measurements were performed using the two-arm multilayer semiconductor spectrometer. Contrary to the results of other studies, we observed several narrow highly excited states (Ex > 16 MeV) of 7He. From the analysis of the continuous excitation spectrum in reactions 9Be(π-, d)X and 11B(π-, dd)X it was obtained first indication that the 4He+3n structure is not present in the ground state of 7He.
