Possible observation of an excited state of the 3H nucleus in the reaction H(6He,α)
Cross sections for the reaction (6He,a) at Η and 12C nuclei and for the reaction H(6He,6Li) have been measured at an energy EeHe= 19.3 MeV, for the first time. The spectrum of a particles from the reaction H(6He,a) contains, in addition to the ground state of the triton, a resonance with an energy £* = 7.0±0.3 MeV and a width Γ=0.6±0.3 MeV. This resonance lies above the threshold for the dissociation t->n+d. It is suggested that this level has a (2n+p) configuration.
