Theoretical study of the 11Li β decay into the deuteron channel in a cluster model

The β-decay process of the 11Li halo nucleus into 9Li and d is reanalyzed within a three-body model. The 11Li nucleus is described as a 9Li+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 9Li + d final channel. © 2011 World Scientific Publishing Company.SCOPUS: cp.j
