Scientists have observed a brand-new and exotic atomic nucleus: aluminium-20. Unlike anything seen before, it decays through ...

Radioactive decay is ubiquitous. It occurs everywhere on Earth and throughout the universe. The most common forms occur when an unstable nucleus spits out an alpha particle, consisting of two neutrons ...

In this configuration, the atom is not radioactive. The team instead used a technique to create an isotope of Lutetium-149, which has only 78 neutrons.

Radioactive decay is a quantum-mechanical process whereby the probability that a nucleus will decay is a fixed value for that specific isotope. This means that for a sample containing a large number ...

Radioactive decay can be easily detected with a photomultiplier tube, but these tubes are sensitive to magnetic fields and cosmic rays that would easily fly through just about any shielding ...

The Sun is changing the supposedly constant rates of decay of radioactive elements, and we have absolutely no idea why. But an entirely unknown particle could be behind it.

Here’s a hypothesis for you: radioactive decay varies over time, possibly with a yearly cycle. [Panteltje] decided to test this hypothesis, and so far has two year’s worth of data to comb over.

The radioactive decay data doesn't quite match up with most other solar patterns, which has led Sturrock to suggest that the sun's core, which produces neutrinos, rotates slower than the rest of ...

Radioactive Decay We can't keep relying on a Vietnam-era treaty to stop nuclear proliferation.
