Atomic excitations during the nuclear {\ss}- decay in light atoms

Probabilities of various final states are determined numerically for a number of {\ss}- decaying light atoms. In our evaluations of the final state probabilities we have used the highly accurate atomic wave functions constructed for each few-electron atom/ion. We also discuss an experimental possibility to observe negatively charged ions which form during the nuclear {\ss}+ decays. High order corrections to the results obtained for {\ss}+/- decays in few-electron atoms with the use of sudden approximation are considered.Comment: 26 pages, 40 references, 6 tables and 0 figure
