In the structure of the title complex, [Cs(C7H4NO2)(H2O)2] n , the caesium salt of 4-nitro-benzoic acid, the irregular CsO9 coordination sphere comprises three bridging nitro O-atom donors, a bidentate carboxyl-ate O,O'-chelate inter-action, a triple-bridging water mol-ecule and a monodentate water mol-ecule. A three-dimensional framework polymer is generated, within which there are water-carbo...

The enhancement factors of the electric dipole moment (EDM) of the ground states of two paramagnetic atoms; rubidium (Rb) and caesium (Cs) which are sensitive to the electron EDM are computed using the relativistic coupled-cluster theory and our results are compared with the available calculations and measurements. The possibility of improving the limit for the electron EDM using the results of...

We investigate the effect of cantori on momentum diffusion in a quantum system. Ultracold caesium atoms are subjected to a specifically designed periodically pulsed standing wave. A cantorus separates two chaotic regions of the classical phase space. Diffusion through the cantorus is classically predicted. Quantum diffusion is only significant when the classical phase-space area escaping throug...

For example, the Chernobyl accident caused the deposition of radioisotopes over wide areas of the Northern Hemisphere, in particular in Europe ( Atlas of Caesium Deposition on Europe after the Chernobyl Accident, 1998), followed by protracted chronic exposure of some millions of people to external and internal radiation. You can see the map of radioactive contamination of Europe after the Chern...

The anion of the title complex, Cs(2)[PuCl(4)O(2)], adopts a pseudo-octa-hedral geometry (2/m crystallographic site symmetry) with two plutonyl oxide ligands in axial sites and four chloride ligands occupying the equatorial plane. Charge balance is maintained by two caesium cations per tetra-chlorido-dioxido-plutonate(VI) anion. Principal bond lengths include Pu-O = 1.752 (3) Å and Pu-Cl = 2.66...

We reconsider the problem of the solid-liquid-vapor contact-line on a disordered substrate, in the collective pinning regime. We perform a replica variational calculation which confirms the scaling behavior obtained from Larkin-Imry-Ma-like arguments and provides a quantitative prediction for the correlation function of the line. This prediction is in good agreement with experimental findings f...
