Abstract : Oscillator strengths for the lithium isoelectric sequence have been critically evaluated and compiled by means of a new generalized analysis which makes use of several types of systematic trends and fundamental spectroscopic constraints. Relativistic effects have also been considered. The data are presented in separate tables for each ion of the sequence from Li I through Ni xxvi, and are arranged within each table according to spectral series. Separate tables are presented for the 2s-2p and 2s-3p transitions, with both relativistic and nonrelativistic f-values listed for all ions of the sequence through Ni xxvi, as well as for a few selected ions of higher nuclear charge. The general tables contain transitions of the type ms-np, mp-ns, and mp-nd, with 2 or = m or = 4 (m is the lower principal quantum number) and 3 or = n or = 7. Since most recommended data were determined from a nonrelativistic analysis, hydrogenic relativistic considerations were applied to estimate when the data would be significantly altered by the inclusion of relativistic effects, and such f-values were excluded from the tabulation.
