The Mystery of the Disappearing Isotope
- Environmental Science
- 2014
A fortunate historical circumstance happened in our country in the 1950’s. On the one hand the recently formed CNEA (the Argentine AEC) counted with a cyclotron capable of producing unknown, until…
Production of 88Nb and 170Ta for chemical studies of element 105, Db, using the GARIS gas-jet system
- Physics, ChemistryJournal of Radioanalytical and Nuclear Chemistry
- 2015
A technology to utilize radioisotopes of Nb and Ta was developed for chemical studies of element 105, Db, by coupling a gas-jet transport system to the RIKEN gas-filled recoil ion separator (GARIS).…
2014 Update of the Discoveries of Nuclides
- Physics
- 2015
The 2014 update of the discovery of nuclide project is presented. Only six new nuclides were observed for the first time in 2014 while the assignments of seventeen other nuclides were revised. In…
Reexamining the half-lives of 195 Os and 195 Ir
- Biology
- 2013
It is argued that the original assignment is correct and the half-life of Os should be 6.5(11) min, consistent with the original measurement, and the value of the only available measurement should be reassigned to 2.29(17) h.

New Radioactive Isotopes for Iridium.
- Physics
- 1950
Abstract : The previous work on this element, iridium, has resulted in the observation of a number of radioactive isotopes. However, on the neutron deficient side of the stable isotopes only one…
CXXIX. Radioactive 186 tantalum
- Chemistry, Physics
- 1955
Abstract The new radioactive isotope I86Ta has been prepared and its decay characteristics determined as follows:— The mass assignment suggested by its production by (n, p), but not by (7, P),…
Observation of 197Os
- Physics
- 2003
Osmium isotope, 197Os, produced with 14 MeV neutrons through the reaction of 198Pt(n,2p)197Os, has been identified and its decay properties have been studied with a g(X) spectroscopic method. The ten…
New Neutron-Deficient Isotopes of Rhenium
- Physics
- 1957
Cerium-132, a positron emitter with a half-life of 4.2 plus or minus 0.2 hours, was identified through its generic relationship to the known daughter nuclide, La/sup 132/. An activity of 30-minutes…
Constitution of Osmium and Ruthenium.
- ChemistryNature

THESE two elements yield volatile tetroxides and by means of these their mass-spectra have now been obtained. Osmium tetroxide was first experimented with; its action on the discharge, even in the…
Selective on-line separation of new Ta, Zr and Sr isotopes
- Materials Science
- 1982
Tantalum 164 to 167, Zirconium 82 to 84 and Strontium 78 have been selectively observed at the ISOCELE-2 on-line mass separator (1) in the TaF4+, ZrF3+ and SrF+ compound form. New isotopes have been…
Neutron deficient radioactive isotopes of rhenium
- Physics
- 1950
A study has been made of neutron deficient radioactive isotopes of rhenium. Using the 60-inch Crocker Laboratory cyclotron, bombardments have been made of tantalum with 38, 30, and 19 Mev…
RADIOACTIVE ISOTOPES OF RHENIUM AND OSMIUM FORMED BY THE BOMBARDMENT OF RHENIUM WITH PROTONS
- Physics
- 1958
Targets of normal rhenium, and of rhenium enriched in each stable isotope, were bombarded by protons in the energy range 10 to 80 Mev. These produced osmium and rhenium isotopes of masses 185, 183,…
