ResumoThe reactions 11Li+CD2→10He+X and 11Li+C→10He+X at a beam energy of 61A MeV have been studied by measuring the triple coincidence of 8He and two neutrons. Experimental data show a peak that can be explained as a resonance 10He, which is unbound by 1.2±0.3 MeV and its width is less than 1.2 MeV. Theinvariant mass spectra of 8He+n show a peak that is consistent with the decay 10He→8He+n+n.
