Using lasers with precisely tuned frequency, λ, physicists control rotational states of radium monofluoride molecules and excite specific rotational levels, characterized by the quantum number, J.

Hickory dickory dock, this nucleus could make a great clock. A special variety of the element thorium hosts an atomic nucleus that could be used to keep time, scientists say. In a first, researchers ...

Physicists have measured a nuclear reaction that can occur in neutron star collisions, providing direct experimental data for a process that had previously only been theorised. The study provides new ...

The hope of the atomic age, when it dawned, was that if radioactivity did not kill mankind, it would cure it. It has done neither, and as time has passed, the fact has become increasingly clear that ...

Shaggy-haired, tusked pigs roam free in the woods of Germany and Austria. Although these game animals look fine, some contain radioactive cesium at levels that render their meat unsafe to eat.
