Abstract

The nuclear {\ss}- decay from the ground and some excited states of the three-electron Li-8 and Li-9 atoms is considered. The final state probabilities for the arising Be+ ion are determined numerically with the use of highly accurate bound state wave functions of the Li atom and Be+ ion. The probability of electron ionization during the nuclear {\ss}- decay of the Li atom is evaluated numerically. We also discuss a possibility to observe the double {\ss}- decay by using the known values of the final state probabilities for the regular nuclear {\ss}- decay.
