Résumé : The excited states in the 5H system, which was produced in the 3H(t, p)5H reaction with a 58 MeV tritium beam at c.m. angles were investigated. The reconstruction of the energy and angular correlations between the 5H decay fragments was performed by using high statistics data. It was observed that a broad structure in the 5H missing mass spectrum above 2.5 MeV was identified as a mixture of the 3/2+ and 5/2+ states. The results show that the 3/2+ and 5/2+ states are either almost degenerate or the reaction mechanism causes a very specific interference of these states.
