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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

MINNEAPOLIS / ST. PAUL–Floating 125,000 feet above the Antarctic ice sheet, a balloon-borne experiment is making an unprecendented second loop around the South Pole, probing the heavens for the origin ...

IN a previous communication 1 I described an attempt to estimate the initial concentrations and partition coefficients of rubidium and strontium. The calculation was performed based on two possible ...
