Analysis of the ${}^6$He $\beta$ decay into the $\alpha +d$ continuum within a three-body model

E. M. Tursunov, D. Baye, P. Descouvemont

The beta-decay process of the ${}^6$He halo nucleus into the alpha+d continuum is studied in a three-body model. The ${}^6$He nucleus is described as an alpha+n+n system in hyperspheri…
