Abstract
We measured the deuteron-emission branch of the β decay of the halo nucleus He6 using the technique of implantation into a highly segmented silicon detector. The method, used here for the first time with a beam of He6 ions, ensures precise normalization; the value obtained for the branching ratio is B̄=(1.65±0.10)×10-6 (6% error). The summed energy spectra of the emitted α 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 He6 ground-state wave function.
