29- CONCLUSION
- The most accurate values for transition
probabilities have been obtained by Branching
Ratio and normalising them by excited state
lifetimes observed by Laser Induced Fluorescence. - One has to be careful when the different sets of
data from different papers are used. - In some cases, due to the cancellation effects or
strong electron configuration mixing the real
transition probabilities or radiative lifetimes
could differ considerably from calculated one. - If there are some difficulties or suspicious of
choosing the best set of data it is better to ask
colleagues from WG Fundamental data.
