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…

Emergence of $^4$H $J^\pi=1^-$ resonance in contact theories
We obtain the s - and p -wave low-energy scattering parameters for n 3 H elastic scattering using the pionless effective field theory at leading order. The 4 H J π = 1 − resonance emerges as a


Experimental evidence for the existence of 7H and for a specific structure of 8He.
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.
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 well
Superheavy hydrogen (5)H.
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.
A phase-shift analysis of the scattering and polarization data for the elastic scattering of neutrons from tritium has been made for neutron energies between 1.0 and 6.0 MeV. Although there are
