6He beta-decays into 6Li causing an electronic rearrangement of the final 6Li atom. The calculations involve expanding the initial state of 6He in terms of a complete set of final states of 6Li. Correlated Hylleraas-like wave functions were used to create a pseudospectrum, which spans both the bound and continue states of 6Li. The sudden approximation with neglected recoil was used. Starting from the 1 1S1 and 2 3S1 initial configurations, the transitions to the final 6Li bound states, as well as the total probabilities of single and double ionization were calculated. The transition probabilities to bound states were compared with those of Wauters and Vaeck . The dependence of energy and probability on the second nonlinear variational parameter was also examined, and found that both show "special" behaviour near beta1=n2. Finally, the total probabilities of ionization were compared with other values [1,2,3].
