Plutonium and cesium isotopes in river waters in Japan
Journal of Radioanalytical and Nuclear Chemistry Articles, 1990Concentrations of cesium isotopes and plutonium in river water samples in Japan, collected during the period from June 1985 to February 1987, have been measured. The total137Cs concentrations in the Japanese river waters ranged from 0.063 to 1.89 mBq·l−1. The portion of particulate137Cs to total was observed to be less than 10 to 35%.

Cesium, americium and plutonium isotopes in ground level air of vilnius
Czechoslovak Journal of Physics, 2006Systematic observations of radionuclide composition and concentration in the atmosphere have been carried out at the Institute of Physics in Vilnius since 1963. Increases in activity concentration of radionuclides in the atmosphere were observed after nuclear weapon tests and the Chernobyl NPP accident.

The 6s-7p transitions in cesium at 459.3 nm (72P1/2) and 455.5 nm (72P3/2) have been investigated by saturation spectroscopy in vapor cells, using a laser spectrometer with 500 kHz bandwidth in the blue spectral range. Isotope shifts as well as hyperfine splittings were determined for the isotopes 133, 135 and 137.

Diffusion and isotope effects in the diffusion of homovalent cations in cesium iodide
Physical Review B, 1988Preexponentials ${D}_{0}$ and activation energies Q for self-diffusion and diffusion of homovalent cations of small radius in single crystals of CsI measured by the tracer sectioning method are as follows: for $^{137}\mathrm{Cs}$, 19\ifmmode\pm\else\textpm\fi{}1.5 ${\mathrm{cm}}^{2}$ ${\mathrm{s}}^{\mathrm{\ensuremath{-}}1}$ and 35.59\ifmmode\pm\else ...

Neutron Nuclear Data Evaluation of Cesium Isotopes for JENDL-4.0 [PDF]
Journal of Nuclear Science and Technology, 2011 For the development of JENDL-4.0, neutron nuclear data for fission product nuclides, 133,134,135,136,137Cs, were revised in the incident neutron energy range from 1 eV to 20MeV by using a coupled-channels optical model (OM), and nuclear reaction models.

Radioactive and stable cesium isotope distributions and dynamics in Japanese cedar forests
Journal of Environmental Radioactivity, 2018Dynamics of the Fukushima-derived radiocesium and distribution of the natural stable isotope 133Cs in Japanese cedar (Cryptomeria japonica D. Don) forest ecosystems were studied during 2014-2016. For the experimental site in Yamakiya, Fukushima Prefecture, we present the redistribution of radiocesium among ecosystem compartments during the entire ...

Alpha decay studies of tellurium, iodine, xenon and cesium isotopes
Nuclear Physics A, 1979Abstract Very neutron-deficient isotopes in the trans-tin region were produced by reactions of 290 MeV 58 Ni ions on 58 Ni targets, and studied by on-line mass separation at GSI. Twelve α-emitters — 107–110 Te, 110–113 I, 111–113 Xe, 114 Cs — were identified.

Efficiency measurements of the isotope separation with a cesium ion source
Nuclear Instruments and Methods, 1965Abstract The radioactive cesium isotopes are to be separated for an optical determination of the isotope shift of the spectral lines. In order to reduce contamination, the losses in the different parts of the machine were investigated. By using a surface ionization source currents up to 12 μA at 20 kV were obtained at the collector with an overall ...

Relativistic mean-field theory on the xenon, cesium and barium isotopes
Nuclear Physics A, 1995Abstract We apply the relativistic mean-field theory to unstable nuclei with Z = 54, 55 and 56. We compare the results of calculations to experimental data of the mean-square-charge radii and binding energies using the parameter set, TM1. The constraint calculations results in an energy curve as a function of deformation with several candidates for ...
