Measurement of Hyperfine Coupling Constants of the 5d²D₃/₂ and 5d²D₅/₂ Levels in Atomic Cesium Using Polarization Quantum Beat Spectroscopy
… hydrogenic picture of the alkali atoms such as cesium [1-3]. More precise experimental results and theoretical treatments are in demand for the alkali elements, especially for atomic cesium because of its wide range of applications. Therefore, it is essential to understand its atomic and nuclear …

Theoretical Investigation of Two-Color, Two-Photon, 6s(2)S(1/2) → 5d(2)D(j) → 11p(2)P(3/2) Excitation and Depolarization Spectra in Atomic Cesium
… → 11p<sup>2</sup>P<sub>3/2</sub> transition in atomic caesium is considered. For quadrupole-dipole transitions the dependence of excitation from the ratio of reduced matrix elements is shown. The experimental method of determination of the value and sign of the ratio is proposed. Comparison of …

Measurement of a Weak Transition Moment Using Coherent Control
… and 7s<sup>2</sup>S<sub>1/2</sub>1/2 states in atomic Cesium. The experimental principle is based on a two-pathway excitation, using two phase-coherent laser fields, a fundamental field at 1079 nm and its second harmonic at 539.5 nm. The IR field induces a strong two-photon transition, while the …

A sub-ppb measurement of the mass of cesium for a new determination of the fine-structure constant
… mass spectrometry measurements of the mass of atomic Cesium with a relative uncertainty of 2 x 10-10. This measurement reduces the uncertainty on the mass of Cesium by a factor of 100, and removes this uncertainty as a limitation on the accuracy of a determination of the fine-structure constant …

Electron Transfer and Other Reactions Using Atomic Metal Anions
The atomic metal anions Rb-, Cs-, Cu-, Ag- and Fe- have been generated in the gas phase and reacted with various neutral reactants in a triple quadrupole mass spectrometer. The metal anions were formed via electrospray ionization of the metal-oxalate solutions and form in gas phase between the …
