چکیده
Lifetimes of twenty-one excited states in atomic Yb were measured using time-resolved fluorescence detection following pulsed laser excitation. The lifetime of the 4f145d6s D1 state, which is of particular importance for a proposed study of parity nonconservation in atoms, was measured to be 380(30) ns.

Experimental Investigation of the 6s 2 1 S 0 ! 5d6s 3 D 1;2 Forbidden Transitions in Atomic Ytterbium Lbnl Preprint Number 42454
We have observed the Stark-induced 6s 1S0 ! 5d6s 3D1 transition in Yb and measured properties relevant to the study of atomic parity nonconservation in this transition. An atomic beam of Yb is excited by 408 nm light in the presence of an external DC electric eld, resulting in cascade uorescence at 556 nm as the excitation decays through the 6s6p 3P1 state. The density of the atomic beam and th...

Radiative decay from the excited 1P1 state to metastable 3P2 and 3P0 states is expected to limit attainable trapped atomic population in a magneto-optic trap of ytterbium (Yb) atoms. In experiments we have carried out with optical repumping of 3P0,2 states to 3P1, we observe enhancement of trapped atoms yield in the excited 1P1 state. The individual decay rate to each metastable state is measur...

The results of ab initio calculation of E1 amplitudes, lifetimes, and polarizabilities for several low-lying levels of ytterbium are reported. The effective Hamiltonian for the valence electrons Heff has been constructed in the frame of CI+MBPT method and solutions of many electron equation HeffΦn = EnΦn are found.

متن کاملMagnetic Dipole Transition in Atomic Ytterbium
We present the results of an ongoing investigation designed to measure the forbidden magnetic dipole transition amplitude for the 6s2 S0 → 6s5d D1 transition (408 nm) in atomic ytterbium. The transition is excited in an effusive atiomic beam with a C.W. laser in the presence of crossed D.C. electric and magnetic fields. The fields are arranged to provide interference between the magnetic dipole...
