“…Comparing our model to the previous theoretical models [10,11,12] we can say the following. A common drawback of those three models is that the α + d scattering states are obtained from an α + d nucleus-nucleus potential.…”

The beta delayed deuteron emission from 6 He is studied in a dynamical microscopic cluster model. This model gives a reasonably good description for all the subsystems of 6 He and 6 Li in a coherent way, without any free parameter. The beta decay transition probability to the 6 Li ground state is underestimated by a few percents. The theoretical beta delayed deuteron spectrum is close to experiment but it is also underestimated by about a factor 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 6 He wave function plays a crucial role in quenching the beta decay toward the α + d channel.

“…This problem has already been noticed and discussed in Ref. 14). Let us just add here that the PM results are not expected to be very small in spite of the orthogonality of the scattering states to the 6 Li ground state, since the 6 He ground state is not the analog of the 6 Li ground state.…”

271The 6 He j3 decay into a and deuteron is studied with different simple models and with a semi-microscopic model based on variational microscopic wave functions expanded in a three-center harmonic-oscillator basis. The latter approach· allows us to show that this decay is quenched by a cancellation between the internal and halo contributions to the Gamow-Teller matrix element. An extreme sensitivity to the halo description up to distances as large as 15 fm is observed. Contrary to several available effective forces, the Volkov force V2 reproduces the measured /3-decay transition probabilities. §
