Cooling and Trapping of Atomic Strontium
We present a detailed investigation of strontium magneto-optical trap (MOT) dynamics. Relevant physical quantities in the trap, such as temperature, atom number and density, and loss channels and lifetime, are explored with respect to various trap parameters. By studying the oscillatory response of a two-level 1 S 0 – 1 P 1 88 Sr MOT, we firmly establish the laser cooling dynamics predicted by ...
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...

متن کاملAtomic masses of tritium and helium-3.
By measuring the cyclotron frequency ratios of (3)He(+) to HD(+) and T(+) to HD(+), and using HD(+) as a mass reference, we obtain new atomic masses for (3)He and T. Our results are M[(3)He]=3.016 029 322 43(19) u and M[T]=3.016 049 281 78(19) u, where the uncertainty includes an uncertainty of 0.12 nu in the mass reference. Allowing for cancellation of common systematic errors, we find the Q...
متن کاملExperimental investigation of excited-state lifetimes in atomic ytterbium.
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.
