Abstract.

Experimental search for superheavy hydrogen isotopes 6H and 7H was performed in the stopped pion absorption on 9Be and 11B nuclei. The structures in the missing-mass spectra were observed in the reaction channels 9Be(π-, pd )X and 11B(π-, p4He)X . Four states of 6H were proposed. Evidences for 7H formation were obtained in the reaction channels 9Be(π-, pp)X and 11B(π-, p3He)X .
