Measurement of the forbidden 6S - 8S M1 transition in caesium with an electric field
نویسندگان
چکیده
2014 The 6S1/2 8S1/2 caesium transition is excited in a Stark field, with a pulsed narrow-band nitrogenpumped dye-laser. It is detected by monitoring the fluorescence light emitted in the 8S1/2 6P1/2 decay. The scalarto-vector off-diagonal polarizability ratio is obtained : 03B1/03B2 = 4.8 ± 0.5. The M1 amplitude is observed through the electronic polarization created in 8S1/2 by its interference with the Stark-induced amplitude. We obtain M1/03B2 = ( 9.15 ± 1.05) V/cm. Using a theoretical determination of 03B1, we deduce M1 = ( 3.11 ± 0.48) · 10-5 |03BCB| /c. J. Physique 47 (1986) 1327-1334 AOÛT 1986,

Dynamic Stark effect and forbidden-transition spectral lineshapes
We report on an experimental and theoretical study of the dynamic (ac) Stark effect on a forbidden transition. A general framework for parameterizing and describing off-resonant ac-Stark shifts is presented. A model is developed to calculate spectral line shapes resulting from resonant excitation of atoms in an intense standing light-wave in the presence of off-resonant ac-Stark shifts. The mod...
متن کاملTwo-photon frequency comb spectroscopy of the 6s-8s transition in cesium.
We report a new absolute frequency measurement of the Cs 6s-8s two-photon transition measured using frequency comb spectroscopy. The fractional frequency uncertainty is 5x10(-11), a factor of 6 better than previous results. The comb is derived from a stabilized picosecond laser and referenced to an octave-spanning femtosecond frequency comb. The relative merits of picosecond-based frequency com...

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...

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 کاملAbsolute frequency of cesium 6S-8S 822 nm two-photon transition by a high-resolution scheme.
We present an alternative scheme for determining the frequencies of cesium (Cs) atom 6S-8S Doppler-free transitions. With the use of a single electro-optical crystal, we simultaneously narrow the laser linewidth, lock the laser frequency, and resolve a narrow spectrum point by point. The error budget for this scheme is presented, and we prove that the transition frequency obtained from the Cs c...
