Abstract
The results of searching for production of superheavy hydrogen isotopes 4,5H in reactions of absorption of stopped π− mesons by 10,11B nuclei are reported. A peak near 3 MeV was observed in the missing mass spectra measured in the reactions 10,11B(π−, t4He)X, 10B(π−, d4He)X, and 10B(π−, t3He)X. A structure caused by two 5H states with the resonance energies E R = 5.2 and 10.4 MeV was observed in the missing mass spectra measured in the reactions 11B(π−, d4He)X, 11B(π−, t3He)X, and 10B(π−, d3He)X.
