摘要：

In view of the current interest of ion trap workers in the lifetime of the 4f(13)6s(2) F-2(7/2)0 level in Yb II which may decay by electric octupole (E3) radiation to the ground 4f(14)6s S-2(1/2) level, we have used a pseudorelativistic Hartree-Fock method including configuration interaction and core polarization effects to estimate the value of the E3 matrix element [4f\r(3)\6s]. The calculated lifetime, tau = 8.4 yr, is in excellent agreement with the recent measurement due to Roberts er al. [Phys. Rev. Lett. 78, 1876 (1997)] (tau = 10.1(-4)(+7) yr). [S0031-9007(98)07314-1].
