Tantalum is one of the rarest elements and has multiple stable isotopes. The least abundant tantalum isotope, Ta-180 is found naturally in a long-lived excited state, a feature unique to this isotope.

In recent years, some large physics experiments worldwide have been trying to gather evidence of a nuclear process known as neutrinoless double beta (0νββ) decay. This is a rare process that entails ...

Scientists have discovered an ultra-rare particle decay process, opening a new path to find physics beyond our understanding of how the building blocks of matter interact. Scientists at CERN have ...

Radioactive decay is the strange and almost mystical ability for one element to naturally and spontaneously transmute into another. In the process, those elements tend to emit deadly forms of ...

Short-lived radioisotopes such as aluminum-26 influenced early solar system heat, water retention and the formation of Earth-like rocky planets, according to meteorite analyses and models.

In contrast to classical physics, multi-particle decay is a phenomenon unique to the quantum world. Magnesium-18 exemplifies such an exotic system, positioned far from the dripline. Spitting out ...

Researchers have observed a rare nuclear decay. Namely, the team measured low-kinetic-energy protons emitted after the beta decay of a neutron-rich nucleus beryllium-11. Researchers from the National ...
