The 0+ ground state of the 10He nucleus produced in the 3H(8He, p)10He reaction was found at about 2.1 ± 0.2 MeV (T ∼ 2 MeV) above the three-body 8He + n + n breakup threshold. Angular correlations observed for 10He decay products show prominent interference patterns allowing us to draw conclusions about the structure of low-energy excited states. We interpret the observed correlations as a coherent superposition of a broad 1 state having a maximum at energy 4-6 MeV and a 2+ state above 6 MeV, setting both on top of the 0+ state "tail." This anomalous level ordering indicates that the breakdown of the N = 8 shell known in 12Be thus extends also to the 10He system. [ABSTRACT FROM AUTHOR] |
