Researchers experimentally searched for the exotic nucleus, five-hydrogen (5H), using a six-helium (6He) beam. They observed a resonance consistent with a 5H state, providing new insights into nuclear physics.

Area of Science:

  • Nuclear Physics
  • Exotic Nuclei Research
  • Hadron Spectroscopy

Background:

  • The existence and properties of exotic nuclei, such as five-hydrogen (5H), are crucial for understanding nuclear structure and reaction mechanisms.
  • Previous theoretical models have predicted the possible existence of 5H, but experimental evidence remains scarce.

Purpose of the Study:

  • To experimentally search for the unbound nucleus five-hydrogen (5H).
  • To investigate the resonance properties of a potential 5H state.
  • To measure the angular distribution and proton-proton energy correlation in the relevant transfer reaction.

Main Methods:

  • Utilizing a secondary beam of six-helium (6He) ions.
  • Studying the transfer reaction 1H(6He,2He)5H.
  • Detecting two protons originating from the decay of two-helium (2He).

Main Results:

  • Observation of a resonance peak consistent with a 5H state.
  • The resonance was found at 1.7 ± 0.3 MeV above the three-neutron plus tritium (n+n+t) threshold.
  • The observed resonance has a width of 1.9 ± 0.4 MeV.
  • Measurements of the angular distribution and proton-proton energy correlation were performed.

Conclusions:

  • The experimental results provide evidence for the existence of a 5H resonance.
  • The observed properties of the 5H resonance offer valuable data for refining nuclear models.
  • Further investigations are warranted to confirm and characterize this exotic nuclear state.
