摘要
A search for superheavy hydrogen isotopes and multineutrons in the two- and three-body channels of pi- absorption at rest on a Be-9 target has been carried out. The H-5 system revealed a broad resonance with E(r) = 7.4 +/- 0.7 MeV and GAMMA = 8 +/- 3 MeV. An indication has been obtained for the resonance in the 3n system with E(r) = 3 +/- 1 MeV. The measured parameters for H-4 are close to the results of previous experiments.
