| Résumé : | 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 with the experimental data. The 5H energy is found to be E ≈ 3 MeV with respect to the 3H + n + n threshold, and the neutron width is Γn ≈ 1 -2 MeV or Γn ≈ 1 -4 MeV, according to the nucleon-nucleon interaction. We therefore suggest that the 5H lifetime should be larger than the 4H lifetime (Γn≈5 -6 MeV). |
