Abstract

The beta delayed deuteron emission from He6 is studied in a dynamical microscopic cluster model. This model gives a reasonably good description for all the subsystems of He6 and Li6 in a coherent way, without any free parameter. The beta decay transition probability to the Li6 ground state is underestimated by a few percent. The theoretical beta delayed deuteron spectrum is close to experiment but it is also underestimated, by about a factor of 1.7. We argue that, in spite of their different magnitudes, both underestimations might have a common origin. The model confirms that the neutron halo part of the He6 wave function plays a crucial role in quenching the beta decay toward the α+d channel.
