Abstract

{}^{6}{He}

beta decay to α+d continuum is studied in a three-body α+N+N approach. The branching ratio for beta-delayed deuteron emission is found to be (3–4)×

10^{- 5}

for three-body

{}^{6}{He}

and

{}^{6}{Li}

wave functions reproducing the ft value for

{}^{6}{He}

with great accuracy. The results are sensitive to the neutron halo structure of the

{}^{6}{He}

nucleus.
