The structure of levels of superheavy hydrogen isotopes 4–6H is analyzed on the basis of a record statistics of experimental data on the absorption of negatively charged pions by light nuclei. Qualitatively new experimental data are obtained for the spectroscopy of the superheavy hydrogen isotopes 5H and 6H. Peaks due to four resonance states of 5H are observed in the missing-mass spectra for the reaction channels 9Be(π−, pt)X and 9Be(π−, dd)X. A structure that is associated with four resonance… Expand

Resonance states of hydrogen nuclei 4H and 5H obtained in transfer reactions with exotic beams
Abstract Experimental search for 4 H and 5 H has been performed in the reactions 3 H(t,p) 5 H, 2 H( 6 He, 3 He) 5 H and 2 H(t,p) 4 H. A resonance state situated at 1.8±0.1 MeV above the t+n+n decayExpand
Multilayer semiconductor spectrometer for studying light neutron-rich nuclei
A two-arm semiconductor spectrometer for registration of charged particles (p, d, t, 3,4He) and their correlations from stopped negative pion absorption reaction is described. The spectrometer isExpand
Search for 4H, 5H and 6H nuclei in the 11B-induced reaction on 9Be
Abstract In the reaction 11 B(88.0 MeV) + 9 Be the energy spectra of the 14 O, 15 O and 16 O nuclei have been measured to obtain some information about their partners in the exit channel — theExpand
Experimental evidence for the existence of 7H and for a specific structure of 8He.
TLDR
The evidence for existence of the 7H state near the t+4n threshold was obtained and the obtained results argue on a specific structure of the 8He ground state containing the 6He subsystem in the excited 2(+) state with a large weight. Expand
Microscopic cluster study of the 5H nucleus
The 5H nucleus is investigated in the generator coordinate method, using 3H + n + n three-cluster wave functions. The model is tested with the 3H + n and 3He + p properties which agree fairly wellExpand
Search for highly excited states in light nuclei with three-body reactions
Abstract Various three-body break-up reactions resulting from the bombardment of 7 Li with 120 MeV 3 He have been measured simultaneously in a kinematically complete experiment. Missing-mass spectraExpand
Inclusive K0 production in e+ e− annihilation at the upsilon resonances
We report on inclusive K0 production in the region of the upsilon resonances (9.4–10.6 GeV). The K0 yield for the resonances and continuum below the BB threshold is found to be constant at 0.82 ±Expand
Superheavy hydrogen (5)H.
TLDR
The transfer reaction (1)H((6)He,(2)He)(5)H was studied by detecting two protons emitted from the decay of ( 2)He and a peak consistent with a ( 5)H resonance was observed. Expand
