There are two coexisting, competing quantum shapes at low energy in 98Kr, never before seen for neutron-rich Kr isotopes, report scientists. The team also showed that these isotopes experience a ...

Andrew Rogers: physicists have spotted mirror symmetry violation in strontium-73 and bromine-73. (Courtesy: UMass Lowell) Physicists in the US have made the surprising discovery that two nuclear ...

An oversight in a radioisotope dating technique used to date everything from meteorites to geologic samples means that scientists have likely overestimated the age of many samples, according to new ...

Scientists have expanded the capabilities of the prototype spaceflight instrument Chemistry Organic and Dating Experiment (CODEX), designed for field-based dating of extraterrestrial materials. CODEX ...

One should not make much of the very small observed range of isotopic fractionation in zinc because only a few samples were analyzed. Allegre, C. Edwards, B. This form of isotopic fractionation is ...

Small clouds of strontium atoms (blue) and rubidium atoms (red) are trapped together. The well-known properties of rubidium can be used to calibrate the applied magnetic field very precisely, which in ...

ISOTOPIC ages by potassium – argon and rubidium – strontium methods have been measured on some Spitsbergen rocks, in the hope of contributing to the Mid-Palægeozoic time-scale and to the understanding ...

A domestically developed proton accelerator, the third of its kind in the world, has taken its first step toward supplying radiopharmaceuticals. The Korea Atomic Energy Research Institute (KAERI) ...

THE age of four samples of granitic rocks selected by the Establishment for Nuclear Materials (Beograd, Yugoslavia) has been measured by the rubidium/strontium method. All analyses were made on ...
