Oscillator strengths for Y I and Y II and the solar abundance of yttrium
Journal Article
·
· Astrophys. J.; (United States)
Oscillator strengths have been determined from measurements of radiative lifetimes and branching ratios for 154 lines of Y I and 66 lines of Y II. These data are used, together with equivalent widths measured on the Jungfraujoch solar atlas, to perform a new determination of the solar abundance of yttrium: A/sub Y/ = 2.24 +- 0.03.
