| 英文摘要 | It has been shown previously that, by using many-body perturbation theory, the electric dipole moment for transitions between exact energy eigenstates dominated by 4f(N) and 4(N-1)5d configurations can be calculated with an effective electric dipole operator composed of one- and two-body interactions. Especially, the one-body part of this effective operator is proportional to the original electric dipole moment, but with a reduced radial integral (5d vertical bar r vertical bar 4f)(eff) = (1 - delta)(5d vertical bar r vertical bar 4f). We obtain the values of parameters charactering the effective operator for all the lanthanide trivalent and divalent ions via a pseudorelativistic Hartree-Fock calculation. The trend of these parameters is analyzed. The impact of the values obtained on the reinterpretation of literature emission lifetimes is given. (c) 2006 Elsevier B.V. All rights reserved. |
