Notes. A number in parentheses indicates a power of ten (i.e., 5.0(− 10) = 5.0 × 10-10).
References for forbidden transitions in the ground configuration: Se0 (Biémont & Hansen 1986a), Se+ and Se2+ (Biémont & Hansen 1986b), Se3+ (Biémont & Hansen 1987). Morton (2000) is the reference for Se0–Se3+ permitted transitions, while those for Se4+ and Se5+ are taken from Migdalek & Stanek (1989), Bahr et al. (1982), and Curtis & Theodosiou (1989). To our knowledge, tabulated Se6+ Einstein A-coefficients have not been published.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
