The β-decay process of the 11 Li halo nucleus into 9 Li and d is reanalyzed within a three-body model. The 11 Li nucleus is described as a 9 Li +n+n system in hyperspherical coordinates. The transition probability per time and energy units measured in a recent experiment can be reproduced with a broad resonance located around 0.8 MeV and a weak absorption from the 9 Li + d final channel.
