Abstract
The lifetimes for the second excited state in21Na and for the second to ninth excited states in23Na have been determined with the DSA method using Ta2O5 and Ta as stopping materials. In the DSA analysis the experimental stopping parameters determined in the present and earlier works were utilized. The reanalysis of some earlier studies has brought very good consistency to the scattered results. Comparison of the observed transition strengths with theory has also been made.
