Abstract

Using relativistic configuration-interaction wave functions, we have obtained length and velocity f values for all lower J=2,3,4 (4d+5s)4 levels connected to the z 4d35p G3o5, and 3D3o levels. Our lifetime results for length and velocity operators are τ(5G3o)=5.16 and 6.53 ns, respectively, and τ(3D3o)=4.67 and 5.60 ns, respectively. These are in good agreement with the experimental values of 5.8-6.2 and 5.0 ns. As we find for hyperfine structure, the 4d4, 4d35s interactions are important in generating accurate lifetime and f-value results. © 1995 The American Physical Society.
