Abstract: We measured the deuteron-emission branch of the beta decay of the halo nucleus 6He using the technique of implantation into a highly segmented silicon detector. The method, used here for the first time with a beam of 6He ions, ensures precise normalization; the value obtained for the branching ratio is B = (1.65 ± 0.10) x 10^−6 (6% error). The summed energy spectra of the emitted alpha and d particles has also been measured. The results allow us to compare calculations from various models, potentially setting strong constraints on the precision required for the description of the 6He ground-state wave function.
